I don't think you can compare the two games. SWTOR is probably the most polished launch I've ever seen. Any MMO with as much hype as a Star Wars game is going to have losses shortly after launch. I can't believe no one has even mentioned theblue screen of death from AOC's launch. The game was unplayable for a large portion of people. Not to mention gem stacking made almost all classes, minus DTs able to one shot any class.
In the grand scheme of things, the Biochem issue was adjusted rather quickly and in group pvp, which is what I believe class balancing should be based on, the balance is fairly even. Is there anything groundbreaking in SWTOR for endgame content... No. The leveling in the game was groundbreaking with voice acting and overall great story lines. Until Tera or GW2 comes out I don't find any other games of any interest.
