Un-nerf Ash Blast

It's been months after the elementalist update. Ash Blast is still useless.

A conditional Blurred Vision with a condition that can't be met in the same line, nor with any skills that approach any degree of usefulness. Earth already has knock downs to not need blind and the requirement for the skill isn't something people look for in their bar unless it's otherwise includes something good regardless of burning. It's not worth splitting for, blind is stronger, and the duration doesn't last the recharge.

This is of course related to Fevered Dreams.

I would prefer invoke lighting.

Saw someone using it for first time in a long time. An earth build without any blind. Poor player didn't know of its nerf.
