i dont know how you guys see it, but the amount of dmg you get from your own team and their feats should be increased in my eyes. so it will get harder to go on a lonly worrior with 4 others, a corner should be then not only something they can hit on you as they wish, also to defend yourself better.
that would be actually a tactic you do in real when you have more then one enemie. and also would force those you attack 2 vs 1 or more to look for the others. the whole combat system is great and mostly realistic. besides that point.

and for the shukogi, when he picks you up for the back breaker. it should be instantly stop when you and with it himself gets a hit. like it is fpr now, when you lifts someone up, everyone can strike as they wish without fear for real consequences, that sucks. first you are up in the air, everyone can strike and then you end up on the ground without any possible defence.
