I'm not a big fan of scenarios, that always lack authenticity, as they are closer to flow drIlls than combat, as the scenario defines the mode of attack.
If I have an opponent on the floor to be kicked, never mind if I have tWo mates with me, then they are not getting up, it's as simple as that, if they do then it's because I was a compliment attacker so that's just a flow drill, practising not going on the floor, particularly if your out numbered would be a useful thing to do, practising getting up very quickly before they get in position is also useful, but lying on you back whilst the people pretend to kick you very hard in the kidneys is just silly, if you get up its because they aren't kicking you in the kidneys
