To be honest I really hope this doesn't catch on as the prefered way of doing the fight (just as solo heal Garuda already kinda became the norm for farms). It's already a pain to get into Garuda EX farm groups because I never tried solo heal (and no one wants to be the first group where I try it, hah), and this solo heal strat sounds like a recipe for disaster (failing to do it properly = almost sure wipe). And it's not like there's a distinct advantage to adding another DPS due to the enrage, and most groups already just go full ranged to null howl anyways. >:
