what do you mean by 'before aoe'?
wasting upfront healing for super weak regen party is a good idea to throw MP away
T2, i thought it might be the only use but after i test the current potency, i'm not even sure it can keep up with the damage. still need to try, ofc
T4, leaving regen effect before the mobs came out is a surefire way to let loose the mobs, if any WHM do it like that, I'm pretty sure it's the reason ppl whining about WHM agro there
Titan's Tumult was already outdamage the old regen potency before, this is just pointless, now hug and eat CureIII!!

no offense, i'm not even sure if I understand your 'before aoe' right
I never have a problem with MedicaII agro before, unless I intentionally do it :\
