Be nice to your tanks? No. Tanks aren't special snow flakes. I dislike most tanks.
When _I_ tank, it's balls to the wall, get this dungeon done and achieving the goal(more exp/JP for your time).
When I dps, other thanks are slow, boring and generally retarded. So of course I'm going to pull for you if your dps and heals are falling asleep. It's not our fault if you have poor skills. Just AOE and keep running, it's not hard.
In regards to LFR, this can be a headache but that's only because the player base is retarded now because blizzard allows it. You don't have to know the mechanics of a fight going in anymore. Just bang your keys while you watch tv. That's annoying for tanks because they have to actually do something. Even it out so tanks can stand there and bash on keys while watching tv like everyone else. That is the only thing that is unfair.
