This is how to fix flash KO's easily

SCI should not have the flash KO system linked to stamina. Here's a better idea.

If your head and/or body damage is yellow you shouldn't be able to get a flash KO, only flash knockdowns and stuns.

If your head and/or body damage is red you shouldn't be able to get a flash knockdown or flash KO, only stuns.

If your head and/or body damage is white you shouldn't be able to get a flash KO'ed, stunned, or flash KD.

This would force players to be more offensive instead of sitting back and waiting for a stuns or knockdown to bail them out on the scorecards because they know it will happen randomly. You'd have to earn your knockdowns.
