If this wasn't already obvious to everyone: The reason people don't pick the Crystal Blast morph is because the AoE damage breaks Rune Prison (a hard CC). This makes Crystal Blast useless for vet content as Crystal Blast doesn't heal or damage nearly enough to compete with using CC on veteran content mobs.
I mean.. the buff is absolutely adorable. But it also tells me Zenimax completely missed the ball on why people don't use Crystal Blast. Don't get me wrong Crystal Blast is like the best skill ever and was that even before the buff. But noone is going to use it unless they plan on never doing solo content past lvl 50.
Buffing Crystal Blast like they have... Really, Zenimax? Really? >.<
