I started playing this game on the PS3 a few days ago and it's really fun. Though I haven't tried playing online yet as I spent 95% of my time going through ToLS. Right now I'm stuck at 45-46F and can't really think of a way of getting passed it. My main (and only) character is Cassandra (have been using only her since SC3) and no matter what I do, I just couldn't beat the first guy in 46F.
I might give online a try tonight and hope that the lag wouldn't be too bad.
