If you including kiting / anti kiting abilities sorcs need to use: knockback, force slow, force stun, force lift, force sprint, cleanse, self heals....lol.
I have 5 50's and I gotta say jugg smash is not hard AT ALL. So many specs need to be that much better of a player to but up those numbers.
Since most people on this forum are assuming that pvp'ers will always stay close to each other to eat smashes, I don't see why it is fair to require sages to kite the same group of clueless people all the time. (At least such kiting doesn't require a very high skill level..)
