I would like to suggest that the person that made the sage changes try healing a 16 person hardmode operation, then once you realize how dumb you are that you try to balance a class for pvp when its impossible to balance for pvp, you break pve content which 80% of the players actually enjoyed, make a viable class useless and annoying to play, would you please quit your job and try something you are qualified for, because you are obviously not qualified for your job at bioware.
another further suggestion, hire someone that plays the game and knows the classes to make any further adjustments to them, it might help.
reguards, from all the sages/sorcs that play the game
