You can watched a skilled fight anywhere like bellator or an asian promotion etc but noone wants to on a large scale because there is no real bad blood or feeling and promotion for that. Thats how all the biggest draws become big draws with the exception of GSP, they all provoke and insult like mayweather and margarito was a good draw and tyson and ali.
Speak for yourself. There's enough people who don't need WWE in MMA. And most of the trash talk isn't "real bad blood" anyways. For this fake stuff there is WWE and movies.
