I was thinking of this, and it would be cool if someone made a mod where the player would have a high chance of tumbling if they start losing health past 50% of their original health. Say you get shot all the way down to 50% health, then if you get shot more, say to 35%, every time you take more damage, you have the risk of tumbling over. This would add realism to those who run realistic servers or whatever. I thought of this while shooting at some bots, kind of a neat idea if you think about it.
