I remember at least one Mmo where we have the option to target the closest ennemy from camera center to the farest.
It's not bad.

The worst in pvp is when i play Paladin. I run in melee in order to be focus but the game only target very far ennemies and i'm just being gangbang without doing anything.

An other problem is in healer mode : outrange allies nicknames are not grey tinted so we lost a lot of time trying to select or heal someone who is completely elsewhere.
