I started doing everything right away, I still attend more BJJ classes, but I try to do one mma class a week, and at least one Muay Thai class. I am an avid BJJ/Submission grappling competitor though. I also have a 2nd degree black belts in Karate and Judo so I do alot of stand up training on my own. Trying to figure out the best way to combine everything.(I had Machida figured out a long time ago, Shogun was the first to implement it.
