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

I was actually pleasantly surprised about this adjustment. Earlier in the thread i expressed my distaste, and how much i didn't want them to implement it because i felt the server lag would effect it in a terrible way, similar to FFXI. But so far it seems to be working very well, and i don't feel like there is any kind of latency messing it up. So obviously they put a lot of the code that handles the interruption and what not on the client side. I'm happy with it overall, now that i see that it isn't a 2-3 second lag to wait to cast like it is on FFXI.
