I know that for the most part we need to be pretty highly specialized in order to function effectively but...
I'm currently holy spec'd with ok pre-kara/pre-heroic gear (+1300 heal, 17.5% holy crit, 70mp5, 9.5k mana). I've been holy since level 35 or so (ret before that) and I sort of want to try out prot. While doing quests/dungeons I've collected a decent set of tanking gear so that I can get my Def close to 490 and enough stamina to have 9-10k HP (if you count prot talents). So, I'm planning to re-spec soon and try it out. But, the problem is, I get asked to heal 70 dungeons a lot by friends and guild mates. So, my question, have any of you tried healing while prot spec'd (just swapping gear)? How difficult is it, is it doable? Or, will I need to do full re-specs each time I want to switch roles (can get kind of pricey)?
