Yeah... Instead of spamming Glare III ad nauseam we will have : Aqua VII turning into Aero VIII turning into Stone IX which proc Glare X which nourish your Blood Lilly.... hey.... Not bad for something made up on the spot Oo
[Edit]
Seriously, i writed this on the spur of the moment.... Now i think about it it's not bad at all.
The proc of Glare X stay up for 15S, or maybe 30S like the RDM and is instant, which fix some of the mobility issue of the WHM.
Also it's a splash AOE with 50% less damage after the first target.
The combo Aqua/Aero/Stone work a bit like a melee combo Aero do 40 potency more than Aqua and Stone do 80 more potency than Aero.
It would be not bad at all.
