Stole a warriors Aggro 5 times yesterday in a dungeon with aoe damage.

That fully depends on the DPS doing the damage, if theyre using their enemity loss ability or hitting too soon before they can overpower (which happens way too much), and on the tank and if he/she is using their aggro holds often enough. That has less to do with the changes and more to do with the players, for that was even an issue in 2.0....3.0.... some things never change
