Personally I don't enjoy having to dps as a healer, and very much prefer spending most of my time just healing, with dps being optional. That's just more fun for me.
That said I recognize that that has never been the style of healing in this game, which is why I almost never play healers in FF. So I totally get why so many healers are upset, but I can't say I am. I might actually give AST and SCH another shot actually...
