[Sage] Fixing Toxikon

[EaMett]

Why shouldn't it be optimal? Both SCH and SGE are barrier healers who... don't barrier heal. Why is it okay that oGCD heals which aren't tied to any resource (mostly) are fine being optimal heals for DPS than the GCD Heals which are tied to a resource, a resource our class exclusive Materia is built around. Toxicon being MP negative would still deter people from spamming it over and over the only difference is that we wouldn't be punished for pro-active barrier healing like we currently are.

I might be reading a little too much in between the lines here but the problem with an upside (or break even) to GCD healing is that GCD healing then becomes optimal or "easy" and you end up just gcd healing everything not worrying about oGCD timer/resource management at all. It greatly reduces the skill ceiling and would most likely make the healers even more boring to play.
You could add timers and management to GCD healing (afflatus) but then it becomes pretty much the same as what we have now with oGCDs (which was also what afflatus was before, an oGCD substitute).
The entire shift is actually much harder to make now that there is NO cost to oGCD healing. That was IMO, the biggest mistake they made this expac. It's fine if it's a niche thing on one healer, but now it's all of them.
