What if: Movement during casting

[Shurrikhan]

What if we can move during spell casting?
I thought about this matter and i think it'll be interesting, the movement im talking about is (walking speed) movement and not running, and it can be cancelled by the jump button.

Making it cancellable via Jump helps a fair bit, but you still then have the problem of being locked out of any new cast until again grounded (about a full second).

Honestly, I'd rather this be used only on a single job I can then avoid accordingly or to see additional options --such as having to hold the cast or clicking a new cast with more than .5s left on cast cancelling the current cast and starting the new one instead, etc.-- added to finely tweak how it feels to play.
