I'm all in favor of separating the Stone and Glare spells. My dream scenario in 6.0 is that instead of replacing Stone with Glare, the latter is a separate spell entirely. We'll still have Stone IV by level 80, but Glare will also be apart of WHM's DPS rotation. Just think of the possibilities. We can have Glare effectively replace Fluid Aura as an updated skill or maybe have it as a instant cast GCD spell like Aero/Dia. Include Aero III back into the mix and an actual water DPS spell like what Y'shtola has in the story, and we're golden. And in the level 90 toolkit, Stone IV will upgrade to Earthquake and Aero III will upgrade to Tornado while levelling.
