I haven’t played PvP seriously in Shadowlands yet because my arena mate can’t come but I do remember in BFA that there were particular tricks, and the destro spec design hasn’t really shifted between BFA and now.
Take these as suggestions since Im not really anyone who could give you serious advice but I will try to help
But can anyone bring me up to speed on how to secure kills in arena?
For warlock this is definetly where CC comes into play. You should definetly utilize Mortal coil for this purpose, at least in some way, it can quite efficiently help you set up kills, especialy make ways for you to freely fear the target.
So definetly use your Coil, your fear and shadowfury. I guess if I were in arena right now, I would Coil into fear and depending on whats going on decide next. I think that in this case, coil>fear>infernal is pretty good as it opens for your burst and you can then pop dark soul and bolt.
Another thing really I would also recommend not using shadowfury unless you can set it up. On it’s on shadowfury isnt very good but you can fear someone and put shadowfury in their path so they get the stun, should you need that for whatever reason, essetnialy the same thing as what I suggested with fear>infernal.
Another thing you can do is that if you have the enemies in the open (which you of course should as warlock), you can secure bolts through either
- Offensive wall (Unending resolve to prevent interrupts)>Dark soul>Bolts
- Cast fear to get kicked by whoever is targeting you baiting them and letting you freecast (still be careful about stuns though)
When do u use ur infernal? Do you open with it, or with shadowfury?
Infernal is a burt CD and you should definelty use it as part of the play when you want to burst, shadowfury I wouldn’t personally use for this, it’s not instant and while sometimes getting shadowlocked could be to your advantage . As I said, I personaly drop it after I coil >fear the target, making it land on their head and then pop your offensives, conflag for backdraft and chaos bolt them.
What do you do when u are trained by 2 dps?
You definetly should make use of double mortal coil here, through havoc. As a destro at this point you will also have advantage with your high damage to put some pressure on them.
How do u deal with all the mobile classes los-ing u?
Well you can’t do that much unless you can catch them in shadowfury or inferal and then fear them at least getting some level on control over where they go.
However if someone runs behind pillar you may always use Cataclysm to try to apply immolates, as as you probably know immolate is the most important thing for securing yourself consistent damage, if you want to go big you can also try using rain of fire to put bit more pressure on them, it won’t kill them but it can be pretty annoying for your opponent.
That’s my two cents, again Im no Cobrak but this is tricks I either found useful myself or seen people using
I know my suggestions probably don’t count for much but definetly at least some thigns that you could try, I’m pretty sure that everything here still works and can be effective, at least to a degree.
