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

what it sounds like to me is he wants to make movement stop spells for future PvP balance. I know this will open a whole new can of worms but PvP is coming mages being able to kite others to death will make them OP.

All they need to do is just have mages casting behave differently in a PvE vs a PvP environment. If you're in a PvP instance, moving interrupts your casts. If you're doing general PvE, you can move while casting. I don't see why it's an issue.

This the reason why I didn't want PvP to be in FFXIV in the first place, BECAUSE of this "can of worms" where now Square has to juggle even MORE balance issues with their classes between PvE and PvP. The two forms of play are so different from each other that it's very difficult to make skills and spells perfectly balanced for both types of play. :/

Edit: However, I remember in some of the old player polls that PvP was in very low demand for XIV, so that does give me some hope that Square won't worry too much about the PvP side.
