First the alerts, which are showing even rare and epic drops, are annoying.
(There is no option to avoid these alerts)
Secondly the virtual joystick only works if you tick 'Virtual Joystick Tracking'.
Thirdly the rogue's 'Shadow Piercer' skill (noxious bolt and aimed shot, too) now automatically aims for vases or other such things more often.
(Further more 'Shadow Veil' often doesn't work. Like 3 out of 8 tries don't cause the skill's effect, whereas the skill is set to cool-down and the mp are used.)
Anyway, I suggest giving an option to avoid the alerts and the skills as well as the joystick should be fixed.
