I have played TERA for 3 years and if you went onto TERA forums and ask the same question you'd be getting the same answers as above (P2W, game broken, lag, fps problems yadda yadda)
Been playing BnS for two weeks now, had a blast leveling, queues are fast (EU Windrest), dungeon queues is cross-server, there's always people running around for OW PvP, there is 0 lag as the game has to be ultra responsive for combos and crap, have had 3 dcs in two weeks though. Apart from that the game runs smoothly on 120 fps, I'm sorry to hear that so many people have old Pentium II that can't run
