I dont think gearing up as healer is a problem. Crafted gear->done. Rest comes naturally. But yeah...as people said above. Healing just isnt fun when you dont have anything to heal and cant do your job you are signed up. Im nowhere a pro and only did about 30 Valigamanda runs this Expansion, some Experts and thats mostly it. Of course i cant speak from Savage Raid Experience, because i lack the time and ambition to sit 2-3 hours a evening before some bosses to perfect it (coming from wow,where i did some mythic raiding. 3 hours for 4 days a week just burned me out from doing "hardcore" stuff).
But yeah...normal content doesnt need healing much...spam the occasional OcD heal and else just your 2 button dps "rotation" isnt compelling.
