Not the worst spec in the game, but definitely a spec that, in the interests of effective team play, should be benched. I've played Infiltration since I started this game and I've been forced to come to the conclusion that it's only a spec for goofing around in, in normal warzones when you want to see pretty numbers on sorcs. Now, I usually play a KC hybrid/KC tank build because force pull is way too much fun and I don't die as fast.
