Lock on feature makes ranged abilities unusable (Controller)

Apologies in advance if this can be fixed in the options but I couldn't find out how.

I've been using snipe with controller and it is borderline unusable. Having your aim jerked 180 degrees from a boss to a random mob is beyond frustrating. Also good luck trying to hit your intended target in a high density area

Please give an option to remove the auto-aim/lock on feature on controller
