I guess that to progress, you would need to add some other MA skills to KM. For example, we do "fight class" which is kickboxing with headgear, shin pads and 16oz gloves. I would also think JJ or BJJ would improve the ground fighting skills. Something like 98% of all street fights end up on the ground...with the bystanders kicking both of you.
