I laughed at that one. WL are NOT weak damage wise, i see it everytime whenever i mess up a combo as BM that many Warlocks are able to 100-0 me.
And tbh WL is a class for beginners, not only because half of the thinking is done by the pet but also because they have way too many resists. But i know that this wont ever change so i just deal with it and keep playing.
