Should I play as a resto druid, shaman or holy priest in WoW(3.2)?

druid healers are really over powered now at everything... they have abilitied to do single target healing and raid heals... nourish is good on tanks and wild growth for party... the priest is getting nerfed next patch and wont do so great pvp but will do about the same in raids... resto shammy will stay the same as always and resto druids yet again are getting buffed so i would go DRUID
