What i dont like about the guard order in spring is, that if you guard a unit with 10 others they just follow this unit, but they dont surround it like in SC.
In SC if you guard one unit with 2 others, one moves in front of it while the other covers his back.
If you guard with 4 units, one unit will cover every direction (left, front, right, back).
This would be much better... also in FF all guarding units are at one point and easy to destroy with areaofeffect weapons.
