If you want to use some stuffs from CMA in MMA or UFC, go ahead. There are 2 ways. One is that the MMA fighters pick up some techniques from CMA and use them in the ring. The other is that CMA practitioners enter the ring following the rules and change their practices to fit the rules.
There are many formats, routes or paths to use the knowledge and practices of CMA. The MMA, UFC, Lei Tai, Kuoshu, San Shou are some of many “formats”.
What is popular will come and ago with the practitioners winning the formats. The rule changes so will the methods or styles of fighting. So now are MT and BJJ. Tommorrow may be something else.
The most popular Kung Fu is Wing Chun. The widest practiced physical activity is Tai Chi. TKD and karate schools are in every corner. MT or kickboxing is in fitness gyms and Tae Bo, too. BJJ schools are increasing.
Tommorrow what styles we shall see.
And yes, Wushu and TCMA remain for the most part in China, Taiwan, Hongkong, Singapore etc.
What is popular today may not be there tommorrow.
What is the direction of the wind today? We shall set sail.
And yet what is your goal or destination?
Your goal will determine where you will be going in the end. The formats, popular trend etc are winds to change course to move forward and yet you will arrive at where you want to go in the end.
If you want to fight, fight and take whatever work for you TCMA or BJJ or whatever.
If you want to be healthier and fitter, then practice your Qi Gong set, Shaolin Yi Jing Jing, Ba Duan Jing, Dao Yin, Da Yan, or whatever.
If you want to wield some swordplay, wield away or sway away for balance, coordination etc. Swordplay actually will help you fight, too. If it helps UFC or MMA fights, if that is important to you, I dunno.
If you want to practice staff (Gun Shu), then swing away. If it helps UFC or MMA, oops, there are no weapon comps in them–
