I mean it is hard to look at extremely cool stuff like ring of frost, druid mushrooms or heroic leap, then realize warlocks will get nothing in the expansion, and not be worried (and jealous!). Demon soul is something we needed but it is just another trinket turned into a spell without any deeper meaning for how warlocks will play.
For PvE we will probably be fine, however Dark Intent is a slap in the face in its own right, not being able to benefit other warlocks, essentially preventing us from giving that 105% that any other class will be eligible to give.
