BUT NOT FALCON'S KNEE Comboing into usmash actually wouldn't bother me... really strong? YES. Safe on shield? NOPE [or it shouldn't be]. The point is that counter spam is currently viewed as too safe, and if you made it only cancellable with a smash attack, it would do a wonderful job of making counter more risky [and also more rewarding, where you want to convert into another move instead of just pressing counter again].
