After neglecting my warlock (my original main) for WoD I'm considering getting back into raiding as a warlock again now for Legion. I've been fiddling around with the specs a bit while leveling and I'm now 110 and need to pick a spec to focus my AP on. I keep hearing how "useless" and "terrible" affliction is for raiding, so my question to you is: is that true? Because out of the 3 specs affliction is the most fun by far and I do tend to subscribe to the notion of "fun>performance". But that only goes so far, I don't want to be a liability to my raid team if affliction turns out to be that bad. I know that affliction is really strong in mythics which I'm looking forward to running.
I appreciate all input and prefer you guys to just be blunt and honest.
