vanilla wow was filled with class faults everywhere you looked, naked rogues ganking full t1 geared warriors, shamans with legendary maces auto swinging to win, paladins taking 1v4s as prot/holy, hunters being able to aimed shot for 95% of a mages health in 1 hit. also the many bugs that came along with the game was overwhelming. To see such a smooth game like SWTOR, I'm impressed.
