This is something lot of guild are facing at the moment.
Emperor Vek’lor running into melee, and start to melee hit the Warlock tank.
It is extremely frustrating, because after so many hours of research, no one really know how it can happen. This problem cause so many wipes, and suddently, next week, you oneshoot him. Nobody seem to understand wtf is going on with this boss.
Note : This can happen at any point of the fight, not only after a teleport (see the video in bottom).
There’s lot of theory :
It’s a position issue. Warlock and Warrior should be perfectly positionned otherwise it cause the boss to enter into a melee state if they are to close/to away. <= After many review of logs, it’s not the case. It can happen even if Warlock and Warrior are perfectly positionned.
The Emperor Vek’lor try to cast “Blizzard” on a target that is out of his Line Of Sight, he run away and start to melee. Can happen on pet and totems. <= Not true, check the clip in bottom at 0:06 when he cast Blizzard into a totem that is in range and start to melee after the Blizzard.
The Emperor Vek’lor take aggro from Shaman Totems or pets (proxy aggro) and enter into melee phase. <= Unconfirmed.
It’s due to your instance ID. You should soft-reset the raid by leaving it for 30 minutes if this happen. <= Unconfirmed.
Hunter pet or Warrior get initial aggro from The Emperor Vek’lor and are out of range before the boss switch to Warlock. <= Unconfirmed.
The Emperor Vek’lor try to explode a bug, but since there’s no bug into his range (probably because melee cleaved them), he start to run into the aggro holder (Warlock) and melee him. <= Not true, check the clip in bottom at 0:16 when he cast explode bug and start to melee.
When a range has aggro on The Emperor Vek’lor (the Warlock), if the aggro holder move (ex : move from 1 yard, strafing to dodge a Blizzard, …), the boss enter into melee state. <= Unconfirmed.
No player should be on the stair. <= Unconfirmed.
Can we have a blue post to know which condition trigger The Emperor Vek’lor to run and start to land melee attack instead of spamming Shadowbolt ?
Example :
We can clearly see the boss spamming Shadowbolt and then suddently move into the Warlock and start melee attack, and then he teleport. Before that, he cast Blizzard and then Explode Bug.
That’s the way things just are.
The theory is that he can’t reach his blizzard target (because target is on stairs) and starts meleeing because of that.
Why would they tell us if there is a way to cheese an encounter? The forum is full of how easy classic raids are, but unknown mechanics and RNG was a big part of the vanilla difficulty.
Go to scarlet monastry. Pull caster mobs, reapeat until the same thing happens. It’s most likely random behaviour built into the game mechanics for any NPC caster.
"You do realize you’re suppose to have a warrior dancing around the caster emp just outside AE range to anchor him in place right? It’s clearly seen on all the old footage of twin emperors. This isn’t a new thing.

There is suppose to be one warlock, one tank, and one healer per side for each emperor at all times. The tank who loses the melee emperor is suppose to just stay outside the AE range but still focused on the caster emperor this prevents him from moving.

Clearly highlighted again.
There is literally nothing wrong with the fight. The fight is working as intended.
I decided to do some digging to further check for the right answer and it turns out it was never broken. There is just lack of understanding."
This is just false.
As is shown by both of the videos, the only time the boss moves is sometimes when the warlock takes aggro from the warrior, in which case Vek’lor takes a step or two, then proceeds to cast Shadow bolt. This is (was) a known mechanic - although it’s absent on classic. Vek’lor going full melee mode, however, was never a thing in vanilla.
Well, this is still ongoing testing but so far this is my guild’s opinion on the matter.
First clear, messy as all hell, several wipes, twins using melee all the time.
Second clear, new tactic.
NO ONE going above the highest step on the stairs as going on the platform seems to trigger the melee behaviour - on that clear we did not see the behaviour at all and thus had zero wipes.
Third clear, same tactic as second, same result.
More testing is needed but going from melee behaviour several times during attempts to not seeing any melee behaviour at all due to a minor tactic change does seem to indicate it has something to do with the platform, perhaps it is a LoS thing with him trying to cast blizzard on someone up there? As standing on the stairs is fine, just not going above the highest step.
In any case, we will continue with this tactic as it does seem to work and we have not seen any melee behaviour since we changed to this tactic.
