Alright so. I ran WoD as Summoner just now. I cant tell if the buff helped or not. I use Ifrit for all the bosses and it did seem to help. I had to use less ED than before. I still ran out of mana, but it certainly felt like it lasted longer. I dont know if its my imagination or not. People in my FC says 50 casts save about 1300 mana than before.
