We currently only have a few targeting options:
Nearest Enemy
Next/Prev Enemy
Take Target
There’s a target center that I hope can be implemented in game. I’ve seen it in SWTOR and I really love its purpose. Basically the interface will just select the nearest target that your character is facing, with ‘facing’ having a threshold of about +- 10 degrees.
This provides the best target acquisition IMO so I really hope it comes!
