I used to be holy, for a long raid fight without a shadow priest, you go through 3 mana pots after spamming FOL, for about 6 min. or so. So we do need a bit more help in that department, EX: mana return, or regen. Although it has been a while since I played holy, and I have to active knowledge with holy in WOLTK. But I do see some holes, compared to other classes. Mostly with the mana regen.
