Played Tera beta over the week-end.
It's the standard MMORPG template with "fixed" battle system (ie more involving, not quite Street Fighter though.), however it suffers from the same flaws as others. (Lack of voice acting to avoid reading, having to find quest hubs and go back to validate, people not sharing the world but competing to get boss, resources...)
Often wonder what's the point of playing a MMORPG, current design make it annoying as you're competing with other players for monsters and barely interacting with them except in guilds...
Can't wait for GW2 and joining in a fight to help w/o afterthought.
