I swear some of you (well one guy) won't stop crying "exploit!" until you have a Square Enix endorsed rulebook for every fight. Just kill the damn thing, does it really matter if it's not absolutely 100% the way SE intended?

Is stunning all ifrit's eruptions an exploit? Killing Chimera up the slope to avoid Dragon Voice hitting ranged? Killing Caduceus without popping slimes? It's not our job to draw arbitrary lines about what is and isn't legitimate. If SE decide to adjust the fight later on then so be it.
