Some annoying behaviors and perceptions

[LalafellDown]

Sometimes tanks will wait for their cool downs before a pull, which is absolutely fine to do. It's better than running into a group of mobs and the healer having to spam cure because he has no cool downs.
Runaway healers are annoying, yes. If you get aggro you should stand still and allow the tank to take the mobs from you.

Some AoE's are situational, a DRG is going to get 3 mobs down much quicker using single target than AoE. Some AoE's are also not worth using the TP compared to just DPSing them down single target.

Nobody is obliged to speak to you, some people are quiet by nature or may have had a bad day. If they're playing well, you shouldn't really be complaining that they don't speak. I agree with asking for tips though, that's a different matter if it's going to affect the party.

I call BS on this. No where in my years of playing this game was I ever required to wait for cool down to pop back up. Even after a wipe in a primal EX run I never waited or asked to wait for a cool down. Its usually a DPS or healer asking to wait because they are squishy. 90% of the time healer is to busy spamming AOE attacks rather than healing me.
Dungeons are face roll easy, waiting on cool downs is pointless.

A good DRG will use proper buffs then spam Doom Spike while adding a Combo Action of Heavy Thrust and Ring of Thorns and maintaining TP on each pull. A bad will spam nothing but Ring of Thorns.

A good healer will run to the tank if they have adds on them and then AOE Holy or Bane on them for revenge. Bad healers run away from the tank for some reason. Tank stops chasing them, healer runs to tank... FFS

Waiting for CDs isn't needed in this game, no. But it's a common need in other games and may be a habit for other players.
