Arenas in WoW have been joke since like forever. You can almost 1shot people, do 1 min cc chains, get silenced, stunned and what not. Its an easy game. SWTOR has better mechanics to it - resolve system, guards. Doing coordinated burts dmg windows was something that took skill - hardswitches in SWTOR e.g., forcing guards/breakers in sw/wow. Now both games are more or less derp. So yeah, arenas in WoW are joke.
