Should probably mention that this should works for NIN: Shukuchi, SMN/SCH: Shadowflare, SCH: Sacred Soil, (BLM: Ley Lines I thikn they'r ground placed? & Freeze?), DRK: placed aoe thingy.
Probably any other ground targeted aoe's that I forgot.
Not sure which ones have issues though, I know Shadowflare and Sacred Soil at least should bump into same issues due to cast times.
