I think that if BW is going to make new advanced class for 50 - 55 the for Sorc i suggest. Necromancer - For Male Sith Sorc Heal. Nightsister - For Female Sith Sorc Heal. I would personally think to add in a new ability for them would be Force Drain, in Which they train the energy from enemies and healing themselves and if force drain kills the enemy then it grants a bonus healing to you. Well those are my ideas, i wonder what the dps would be because the advanced class for 50-55 would focus more on what skill tree you picked, whether it was dps, heal or tank.
