I hope these beta weekends don't backfire. It takes quite a few hours to really get into the meat of the game. I don't know if a weekend is really long enough, since it doesn't have something flashy like TERA's combat to really "wow" people right off the bat.
They added in active dodge. It's pretty awesome. Combat's not pretty to look at (what game's, besides TERA, is?) but it definitely feels a lot better.
