How would you get killed by the above poster? #2

Munkosh and Peiling duke it out on what is presumably a battlefield for several minutes, both utilizing their surroundings, other combatants (Alliance and Horde alike) and each other's momentum to the point that it could be straight out of a Jackie Chan movie... with two Jackie Chans fighting each other.

Eventually however, Munkosh is victorious. Details are sketchy as to what exactly was the decisive factor (for the candidates are many) but regardless, he is the one to survive the encounter.
Peiling is quite simply too fast for Valratho to shut down with a Void related spell. With a jab at his throat to silence him, the rest is over in mere seconds.
Taking into account the recent dreadful evens, Illumielle's will is weak to oppose Valratho's spell, and her mind is easily controlled. Her consciousness is filled with mourning and despair, and then the Mindblast spell ends her.
Mistaken for an enemy, due to recent events warping her perception of reality, Illumielle wraps Elyssa in a cocoon of thorns. The latter, confused does not even struggle as she is veritably ripped apart by an unforgiving embrace.
It would most likely be a misunderstanding. Darkian is a scary, imposing creature even when he tries to look unthreatening. And his race associates him with the Alliance whether he likes it or not (he'd prefer to be neutral and independent, but when you're "demon spawn" you have to work thrice as hard to earn people's trust). He'd be searching for some bandits he's been sent to slay, and the rogue who happens to be hiding in that building may decide to attack first before he gets revealed through Spectral Sight (ironically, Darkian's is not very good).
As Darkian is gliding towards a troll headhunter his wings disapear mid flight and he falls straigh on Malaficus Shaikan neck as he was attempting to kill an orc grund.
Void Tentacles (TM) gone wrong.
Void tentacles gone right.
"Nendrovus' Genuine Nightwell Water™" turns out to be a discarded batch of elixir that is used for neutralizing the renegade felborne, found and bottled by Nendrovus outside Suramar. While it is perfectly safe to be consumed by everyone else, it has the same lethal effects on demon hunters. Being unaware of any of those, Savoren decides to try out that Nightwell water he bought from Nendrovus, only to have his insides completely scorched.
By turning to look at the elf's blazing eyes that caught her attention as he walked past, and subsequently clumsily cross the road into the path of a stampeding brutosaur caravan!

Splat!
After a lengthy conversation, Gilrom would convince the beautiful Draenei to a duel. A true dance of death and between two different forces of existence.

It would be a sight to behold: Dark, necrotic energies colliding with the pure and radiant energy of the light, the world around them seeming to fade away as they both fight for their lives with an equal vigor and passion, neither willing to let go of a fleeting and precious thing that is life.

Ultimately however, Gilrom would find the light energies to be too powerful even for his formidable defences and would feel immense pain as his skin and soon his insides are burned by the holy fire. He would start laughing maniacally, enjoying the intensity of the pain and feeling alive one last time before his earthly form would turn to ash and his soul disappear into the other side.
Rorick would, reluctantly, join Gilrom on some sort of adventure. Maybe some Horde-slaying is involved? Little does he know that Gilrom sees him as totally expendable and is willing to sacrifice him in order to kill a great number of Horde grunts.

To add insult to injury Gilrom even raises Rorick to be a mindless ghoul named Tombchewer or Bonefetcher.
Rorick would step out in front of Zirael and loudly challenge her to a fight to the death!

In turn, Zirahael would activate her demonic powers, wings spreading and rising to 14ft tall; to loom over the human!

But as Rorick points his mortal, steel crossbow at her, the Demon Huntress would be unable to keep up the act anymore; whereupon she would promptly giggle, fall to the ground, and burst into hysterical laughter while rolling around.

Wiping acidic fel tears from her nonexistant eyes with a clawed finger, she would laugh for so long and so hard; eventually her supernatural body giving in and she goes stiff - dead on the spot!
As Nisterious Nigglesocket toddles up Roifa Ashlock one day, prepared to pitch her dating agency, Nisty's Scientifically Selected Soulmate Service, it appears she has chosen the wrong day to do so, as Zirahael had chosen this moment to finally launch herself at the Undead individual in retribution for constant bullying over her deformed physical features …

… the Demon Hunter's typically brutal, over the top opening salvo filled with many area of effect styled abilities unfortunately catches the Gnomish romance expert, whom Zirahael was not aware was even in the vicinity.

The outcome of the ensuing battle between Roifa and Zirahael is unknown, but Nisty's fel charred remains are the first casualty of said confrontation.
Zhanag makes the mistake of signing up for the Gnome's dating agency, figuring that he might as well try and find somebody even if there is a war on. This ends catastrophically, as the service matches him with a Pit Lord who somehow got into the system. The results are foregone and messy.
The Pit Lord put in the database and matched with the Draenei was the work of some Illidari spymasters that were really unhappy after the fanatic killed off a certain well-educated and relatively nice Demon Hunter that also happened to be a good field scout and even a decent diplomat.
Zirahael's brilliant and flawless plan to slay the Pit Lord by getting him into the Gnome's Dating Agency with his certain doom was foiled when the Spymasters changed the demon's date from the original Lightforged Badass Draenei Paladin 'Muraad the Epic Demon Killer' to a piddly mage called Zhanag - without informing Zirahael.

Thus, when the Pit Lord met his date; Zirahael sprung her 'trap', activating her powers to engage the Pit Lord in a kaju-style battle!

... only to suddenly wonder what happened as her wings were clipped by the unmolested Pit Lord's Warglaive, and a panicked spell from Zhanag missed and teleported the giant but wingless Zirahael a few thousand feet above Azeroth's surface.

There were a lot of curse words; both in Demonic and Darnassian; all the way down...
Sad times for poor Dug, he had just got there. Picking up some lumber here and there. And finally, his lunch break.

The only time he enjoyed, sitting down in an opening, the peon would eat a piece of dry boar meat, and wonder to himself. "Is this it? Is this my life? Am I not destined to something more?" The questions would be answered by the gods of fate itself, as he got instantly killed when crushed by a night elven demon hunter that fell from the sky.

Alas, poor Dug, nobody really knew him well.
In the middle of a long battle, a failed ambush on a horde outpost, Maedius steps foot on a stone bathed in blood, the blood of a puny peon (Duhg). But as faith has his ways, his exhausted legs lose balance. He slips - the back of his head hits the stone, he looses consciousness - the world around him starts to feel hot - IT BURNS! - Flames everywhere!
He wakes up admits a sea of flames - Teldrassil is burning - the laugh of the banshee queen pierces through his mind.
Maedius screams! ...
His scream echos in the dark and silent night as he realises it was just a nightmare.
The morning sun is rising over the area - a new day has dawned!
A new day of revenge!
While working togather to take down a nearby horde army maedius cast starfall and end up hitting malaficus who was wounded from slaughter a million orcs.
Accedently killing him.
