I have been shadow for as long as I have had my priest and I am interested in raiding with my guilds alt team. The only problem is they are short on healers and I have little experience healing and my gear is all setup for shadow. Experience i'm not worried about, thats an easy fix, but I havn't even bother collecting any gear for healing.
Since shadow dps gear is basically stacking spirit for hit and haste everywhere else how viable is it for healing? Will the lack of crit/mastery pose a problem? And on that matter would Disc or Holy work better for that kind of gear?
