Everyone is acting like some kind of expert on classes when in fact, noone really knows how good or bad the souls are or will be.
I have had nothing but success in pvp with a sin/riftblade/bard build. Pop in and out of combat with the plane shifting abilities of the riftstalker.
Yes I die but guess what everyone else does too. Theres alot of awesome potential to play every soul of each class the way you want. If you don't care to utilize the opportunities available to you by the 2 other souls at your disposal thats your choice, but don't come on here and whine about how much this class sucks, when then game is barely started.
