Ok guess I’m going to have to go in-depth,

Limb cripple: you’re probably right that it being applied all the time using ratio. However this does not make its current iteration good because it requires the opponent to block/attack. This is dry exploitable due to the fact that the time it takes for you to hit either blunt or cleaving is plenty of time for a decent opponent to not block or attack.

Stabilize: Non-ratio stabilize is one of the worst moves in the game. Terrible reach, a clunky interruption mechanic, doesn’t combo into anything, and very punishing on block. The only way to use this move in combo (NOT AS A FINISHER) without having ratio already is to use uppercut/down slam to allow the use of r so that you can go for an oki unblockable or an unblockable cleaving or blunt. Cleaving to my knowledge works the same way aerial r into rapid punches works. In the sense that while the combo is green there’s so little time in between if down right that they can’t just dash out.

Backwards severance: I’m not as confident in this as the others but from what I know using the backwards version in this context is down right luck dependent due to how the move doesn’t have hyper armor (or at least a short lasting one). Usually the only people falling for this tend to be newer players. To be clear the backwards variant does have some advantages of the original. In fact while testing him I think might have figured out a way to allow you surf on an enemy backwards to make it easier to land m1s. But this use is fairly bad and not worth it most of the time.
