I've bought Rakata Enforcer leggings for that reason (as healer), and i plan to buy just the ones with the high cunning stat.
Enforcer has 122 cunning in Head, Gloves, Legs
Medic has 122 cunning in Boots, Chest
So you could just mix chose two sets, because tbh, the setbonus on the healing set is pretty useless anyway, 4 set is entirely useless because i never use kolto pack, and 2 set is kinda meh because i hardly use kolto cloud and its not a huge difference either.
As for the enhancements.. they have bad stats in all items lol... I have all mine swapped out with columi grade crit\surge or power\surge enhancements. Giving me about 300 power rating, 40% crit 91% crit bonus (selfbuffed).
