If there are plans to have more fights like Titan, that are high-movement, please give black mage the ability to run again while casting.

I think a good way to balance this out is, it's only PvE. Because the original reason it was taken out was for PvP, yet has it's own rules. So why can it be reintroduced?

Maybe -20% on the spell damage if you move while running.

Make jump the way to cancel a spell.
