To be better at MMA, you need to have different options in terms of skills that you can use on am opponent. So, I don't get the reason I would expect those involved in only karate to spend the same number of time.

There is more in Mixed Martial Arts. You will need to learn a bit of everything! As long as you wish to become very good, you should spend more time learning the rest. That is the way to come on top.
