Probably my input would mostly be ignored. But I just prefer medium or faster. At fastest it's almost impossible to recover from a first stab. I notice also many more stuns. Chambering does go smooth with fastest I must admit. It's also much harder to clutch as many people just spam with this speed and throw a shit load of stabs in.
You could say "then learn to block!" But blocking 5 enemies at the same time spamming stabs isn't really possible, unless you're the guy from the matrix.
