i dont see this being brought up, and im not exactly downplaying any of this, because 220 is pretty poor...

but even without all the math behind it, just want to point out something;
E.Combo+holy/flare+scorch= 2270 potency for 80/80 mana
E.Rprise x10- 2200 potency potency for 100/100

sure, thats 5 GCDs and 20 mana difference, but.... how much more potency can we give it before it becomes our only spender? Like whens the realistic cutoff point? I'm not a math dude, so im genuinely curious.
basic division tells me 280-290 potency overtakes the combo at 80/80 mana for total spend mana/potency, with only 2 GCDs difference (a thunder/aero+proc, since scorch replaces jolt). and much more than that makes it more potent than our spells baseline.

....so yeah, im curious. Whats the magic number for us at this point where it's useful for a dump, but not better than the combo we're trying to dump for?
