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

[Krausus]

We will set up a specific key for halting spells, so we did not implement this spec as a method of halting spells.

Am I reading between the lines but does this mean that once the specific key is implemented, movement as a means of halting spells will be removed? ...so we did not implement [moving] specifically as a method of halting spells.

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.
