Signed. I play a Sith Assassin and up until level 35, I had little to no problems tanking in my DPS gear -- only having the tank stance on was sufficient. However, now that I'm getting closer to 50, a dual/tri-spec is a must to perform adequately and not overburden the healer and the group since I don't have access to the talents available in the defense tree. Rift has implemented this function; WoW started it. There's no excuse from Bioware's development team for not implementing such a functionality. If SW:TOR is trying to be at the forefront of the MMO genre, this should be their top priority. But judging from the lack of any decent end-game activities, a terribly designed AH, and sub-par PvP, I'm not holding my breath.
