Only played will level 7. Was an Nightblade Archer with Syphon. Was quite easy. Died a few times, mostly due to dealing with the movement controls. But really, I could take on several enemies at a time without much issue.
I just can't get over the movement controls. W.S.A.D, but no Q or E. Yeah, keyboard turners are shunned, but I always used a combination of QWEASD + Mouse. Gave me excellent control. Taking away the Q & E keys and replacing it with a mouse which is locked to your turning really doesn't gel with the way I play games.
