This and DD are great dungeons to teach people to stop acting like idiots on runs.In all honestly they should be manditory and not optional like the currently are.
The whole concept of AV is ok you're lvl 47 you've been through various dungeons by now you should have gotten your act together.

Its by no means a really hard dungeon.Its just more punishing than most for deliberate bad play.
And this is what causes most of the wipes.
Dps trying to act smart and run ahead of the tank,The tank being overconfident and pulling more than they can handle and not bothering with mob positioning and being lazy about useing cooldowns or the healer who's gotten to used to semi afk healing and not paying attention to anything going on.

Its great because it doesnt just punish new players for not learning properly.It punishes all those crappy lvl 70 players who never learned how to play their role properly.
