Kick Suggestions

For effects on a successful kick, I'd say a knock down mechanic. If used on an enemy with a shield, then if stamina is in the game, have it reduce their stamina.

If my Friendly Fire suggestion is also accepted by the community, I think the same above rules should apply, except with the addition of two options you as the character can take when kicked into the knocked down position.

The first being a simple standing up animation, and the second being a shorter than normal roll to feet animation that will go in any direction of the left analog stick.

I'd also say that if you or an enemy's stamina goes to zero (if stamina exists in the game), it should cause a shield being knocked back animation which leaves the player or enemy defenseless.
