I think theres some cases where locking into a specific direction can be handy. Just like most graphics applications where you can lock into the 8 directions. (up,down,left,right and diagonals between) .Im actually more interested in a 12-direction (like a clock) lock. I find that sometimes grid snap fights distance snap a bit too much, grid snap also doesn't help much when trying to do angled combos.
