Moving will be made to interrupt spellcasting at a point in time...

I'm also used to standing still while casting in other games i do it in ffxiv lol. This really is not a bad thing, I can't seem to think of any wizards who cast spells while running around.

I would rather have jump cancel spells move than just running.

It's not just wizards you need to look for, it's anyone who uses any kind of magic/energy/ki, because generally they are linked together.

How boring would most be people if every character had to stand still for even the smallest attack. Goku Instant Transmission Kamehameha, Naturo's running Rasengan, Ichigo's dashing Getsguga Tensho.

Sorcerer Orphen could do some spells that were low level while moving, but his big ones he had to stand still.
