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

[Celtodeno]

Being able to run and cast is much more fun than standing in one spot and casting. It adds a layer of strategy and makes the game a bit more fast paced and exciting for me as a caster. This is one of my favorite parts of casting. I love being able to move around and kite a mob or a group while casting. IT'S FUN.

The benefits to still-casting are......? FFXI players like it?

Can't wait to play Pvp and get mowed over by every DoW while i stand still waiting for my 5-7 seconds spell casts.

Why mess with a good thing? It's not broke Don't fix it. Not exactly a progressive move Yoshi.

Pick a button for interruption, not my movement.
