what you are saying about the encounter's mechanics is outright wrong Szarala. there is really no RNG involved when you are playing it correctly, no gambling whatsoever. this strengthens me in what I said before, pretty sure you can't beat the encounter yourself and are bitter now that blizzard made an "unfair" encounter and turn this frustration into "but blizzard is stupid anyway" arguments now.
also, if you make it out like you do, then of course it's not a warlock specific encounter. you can drag that even further by saying "lol you need a stun? all classes have stuns! you need dots? lol shadow priests totally have dots". it's just a stupid way to put it though.
again, why is it that for over 10 pages different people told you that they liked the encounter and think it's a decent test of warlock skills and you keep arguing against it? is there a point where you will see that you are in the wrong, or will you keep this up for another 20 pages?
