Full Moon kinda feels like a Destro Lock thing too given the Chaos Bolt-like cast time. It also has the problem of causing Boomkin to be less mobile and you'd have to make it Astral Damage if you ever wanted it to benefit from both eclipses... which means you'd have the same problem as Destro with getting locked out of multiple schools on an eminently interruptible spell.
Though Full Moon is certainly cool as shit. While the spell morphing is unique, I honestly wish it wasn't tied to New/Half Moon.
