I'm laughing my ass off at all of these comments about how they get mad or they think a healer is leeching because they're not doing something every second of every minute of a dungeon.
Let me explain this to you. There as multiple jobs in a group. dps and dd deal damage, tanks soak damage, healers heal the damage away. Without the tank and the healer you're not running much of anything, so that's not much of a leech. DD and dps are a penny a dozen in this an every other MMO in existence, if anyone could be considered a leech, it's the job with the least amount of responsibility in the group. That's DD and dps. Or maybe you like it when you die in a dungeon because you didn't have somebody there sending spells your way to patch up the damage you take.
I'm not saying a healer that dpses or doesn't is either bad or awesome, thats up to the person. Personally my dps when I run dungeons isn't that great in comparison because I'm breaking rotations to chip out heals here and there, and I also often dont use cleric stance because I'm not sacrificing potency in the off chance I need to quickly pull somone out of some shit. I also do other things like keep shields up, get rid of debuffs, pick up keys or open chests to speed things along. So in the case that I do dps it's simply because I was bored. certainly not because I felt compelled as part of my responsibility of the group to help kill things. My responsibility if to keep everyone alive, yours is to tank or deal damage.
All that being said, I never 'just stand there' I'm always doing something and yes usually it's throwing dots if it isn't healing. This game is a bit different in that it actually allows healers to do things other than perpetually cast heals, and that's kind of nice. But seriously? Calling healers leeches and mooches? You people just like to end up face down in the dirt dont you?
