Which is why elves came to this conclusion that warlocks are extremely overpowered.
Well, as a bird, i must admit, warlocks are OVERPOWERED against Melee classes, which, unfortunately is not new. Ranged classes have always had a huge advantage over melees.
Also, warlocks are in fact, quite weak against strong healers. (any pro shaman/druid/necro/priest)knows that the only way to kill a warlock is to kite) As for rangers, they need strategy and timing.
As a bird, i would like to say that it is quite easy to trick warlocks into using their skills. I prefer using the "run in-fall back" tactic, when you are 6 yards away from a warlock i ALWAYS fall back.(Remember, dark circle range is 5 yards so watch out ;) fear is 4 yards, ouch) In most cases they would've thrown their dark circle, 1 skill wasted. This is when you or your partner strikes, the warlock would be able to fear one, so be prepared. If there are two warlocks...oh dear god)
Pst: im a bird
