Re-roll as an Operative, healing as a sorc is pointless and you would make a far better (any other class) than this deliberately gimped one.
I have all three and actually prefer my sorc healer. Even without the bubble stun I regularly get top heals and have surpassed operative healers several times. Off the top of my head I can only remember one time an operative beat me and that player was from one of the top pvp guilds on the server, and even then it wasn't by a lot. My point being, sorc healing in pvp is hardly "gimped" and you don't have a clue wth you're talking about.
