That kind of attitude is precisely what the point of that part of the article was about. Warlocks have small mana pools compared to every other caster class, we have much greater mana costs per casts than every other caster class. You think you have to burn your gold drinking, well it would cost us four times as much to keep ourselves topped up in that way.

Sure if the group has stopped for a mana break, and a Warlock is standing around at 5% health waiting for you to finish and not eating then he/she is taking the piss, but our class is designed around the understanding that we make good use of life-tap. Also, as ISL destro, or Afflic we generate pretty awesome amounts of self-healing, so it's not like we're not helping you out at all.

Noone's expecting you to manage our pets for us, but there are limits to what we can do. I don't expect you to prioritise my pet over any member of the raid, just to be aware that he is part of the raid dps and he is giving you free spirit and intellect, unless I'm dreadful, he's not going to be asking for much. If you struggle that much with healing in that encounter, let him die first, if not you're doing yourself no favours by ignoring him.

We appreciate healers more than most, because we know that we depend on you for dps, even if we're taking no damage. We hand out healthstones, and you're always the ones to get our soulstones, just understand we need a little more love than mages :)
