I hate the PvP in this, I've done it a few times on a tank healer and DD, but it just feels like a game of tag not a duel.

One major thing I think is an issue is that tanks can't tank, if they changed it so abilities with increase enmity instead cause the opponent's target to switch to the user and provoke to cause the enemy to be locked onto the target for a set duration I think it would really go a long way to fix it.

Tanks would be able to be a nuisance that the other team will want to kill first so they stop screwing with them, which would bring both teams together to see who can tank better who can heal better and who can DD faster. rather than running around in circles playing catch the healer!
