Stat Priority as a WHM.

Despite the overwhelming support for det, i find myself preferring pie+ss.

While it is true that huge stacks of ss only really become noticeable on spells with longer cast times, i find myself in situations where i'm using those spells often. Final coil in particular, where i'm being expected to do extensive solo-healing so our sch can dps, I've found that reduced medica/medica II cast time invaluable. (i'm looking at you T11 add phase) That fraction of a second can definitely make the difference when i'm being targeted with three laser cannons, or i have to interrupt a cast to get out of a gravity puddle. Also solo healing definitely has me casting enough during certain points in each fight that i notice the benefit, and i almost never need a ballad.

Honestly tho, just having a healthy mix of all of them is fine. If you want to min/max or find it enjoyable, that's great, but 20-30 extra points on a cure isn't going to save anyone (i say 20-30 because you're bound to have some det anyway) All this isn't to mention how absurdly expensive det materia is when discussing novus builds or crafted accessories. Can i make the gil to buy it? Sure. Do i have the time to SB it myself? Probably. But that opportunity cost is just way too high, at least for me.

TL;DR - You're going to be able to heal all content just fine with the mixture of secondaries that comes from any given gear set of max ilv.
