I've been playing pretty hardcore a stalker/ss duo. Took quite awhile to get everything set up well to play comfortably in this game as there's so much dodging and I was trying to avoid the one-key-both-toons issue, but it's finally starting to get smoother. I can't see it being viable for dungeons or anything much harder than leveling, but I'm happy with that as that's all I really wanted. In the end I'll have a good grinding/farming pair and one can sit in the house to click harvest nodes while I'm on raids etc. Game is more fun to me than anything that's come out in awhile and has a lot of depth to it so far. Dungeons are hard enough, raids should be challenging.
