Its called sub target and its amazing, I don't know why I see people complain about this... It's there so you can keep a main target and still have the ability to cast on other targets without dropping the main one... Example.... I have 10 mobs in front of me I want to focus on one with damage spells, and someone in my party takes a hit and needs a heal... i can utilize sub-target to cure the party member without having to drop the enemy target and toggle through all the enemies to get back to the one I was attacking. Or maybe I want to sleep a incoming mob etc ... without losing the one I'm casting damage spells or w/e on... anyway I couldn't disagree more with the idea of getting rid of it.
Maybe if you use mouse to target things I could see this being annoying but if your using keyboard onry or a controller... this feature is amazing in my opinion.
Excuse the haste in which I wrote this I'm due to be somewhere but wanted to respond quickly.
