As a sorc healer, i must say sorc healers needs a buff.
Sorc healers are very imobile and as it is now, we die in a few seconds, even with bubble self heal and medpac, to a marauder/operative(and the republic equivalent ones) and with the lack of mobility we cannot get away in any way. I find myself to be VERY usefull in groups but in the same second a DPS finds me and goes on me im as useless as a rock. Honestly, i dont believe HEALING needs a buff as long as healers are mobile. But sorcs really, channeled/cast time on every single heal(~2.3 seconds for dark infusion our main source of healing and a channeled 2.7 seconds for intervene which is our second best source of healing but it also allows us to keep up our force) I have not played a merc but i believe they have a few usefull instant heals, and i know that operatives have only one usefull heal with cast time. So really, buff healing or make sorcs more mobile.
1.2 was good, just a bit too harsh for sorc healers.
