I've gotten used to having to stop before casting after this weekend, but I agree with Kikosho that we should automatically stop when we select a spell instead of having to stop before selecting it. After a split second if we are still holding the direction we could continue moving as before and cancel the spell. It would make it feel a bit more fluid and it was actually how I was expecting it to work.

I'd like another targeting mode where facetarget it automatically executed before any spell, yes please!
The only thing I have against this is if we ever get enemies with Gaze attacks (like FF11's petrifying Baleful Gaze that cockatrices had) it might become a nightmare playing a caster with an auto-turn target mode.
