been playing it solidly since it's pre-order event (lvl 26 elin archer), it's great

cb was kind of meh, didn't get to keep anything so really didn't bother with it. now that you get to keep everything for launch, a lot more fun. combat system rocks, soloing bams (Big Ass Monsters) is edge of your seat kind of thing. one wrong move and you could be paste. animation details in everything, landscape details, skills, glyphs that modify skills, even basic attacks.
and no auto attack or auto target. pots have a 60 sec cd so you can't just gulp pots to stay alive everything relies on you knowing how to move, dodge and when to attack without leaving yourself open. huge world, variety, graphically beautiful and fun to play.
the downside is en masse and their westernization schemes...but might be able to live with that.
