According to the article, seems that distance and direction will be major factors, as well as movement, so it will be interesting to see how that works with their party vs. party concept. SE has a history of coming up with new systems that sound great on paper but are no fun when implemented, so i'll cross my fingers that they keep the fun factor as a priority.
Is it just me or do these classes sound a bit, limited? All your melee seem to be able to tank, and all your casters can nuke and heal. The archer seems to be the only role that doesn't seem to share much with anyone else. Granted i'm sure its not all the info, but I'd be very dissapointed if this was all the variety you got in the game. Overspecialization is half the fun.
Anyway, has anyone even got into the beta/alpha or whatever, cause other than the press who went to Vana'fest - I haven't seen anyone saying they did.
