Targeting in this game is so much fun!

[Deathgasm]

I'm not sure it's the worst targeting system I have ever seen because I can't remember yet, but it's the worst as far as I can remember for sure
Anyway, like in mass PvP, it's better to tempt to target directly with the mouse than using the clumsy TAB that will select a mob in an other pack on the other side of the road that you are non even facing or that is simply 25 meters away from all the pack in front of you.
Also with lag, instances are a lag fest, it's an horror, if you have a key role it can be a real problem. It's like switching target was submitted to the GCD sometimes.
