I went to one Karate school, one Wing Chun school, 2 JJJ schools and all Sensi did not have a positive view of MMA - they classed it as a sport rather than true Martial Arts which is fine but slightly narrow minded. At the very end of the day you have enjoy what you are doing and if you are doing it for self defense then hopefully it's relevant to different situations.

At Karate & Wing Chun I asked what should I do if the fight ends up on the floor? Both times I didn't get a satisfactory response.

At JJJ they covered absolutely everything, standup, ground, weapons etc. I just fond the pace slow and the belt system slightly restrictive. I grappled with someone a belt above beginner and after I submitted him twice he complained that I wasn't wearing a GI so he couldn't grip me properly...
