I follow competitive COD more than I do the FGC. I watch Parasite's stream frequently and am familiarized with just about every professional team. Honestly, they pop off more because the games i.m.o are more competitive. The community is much larger making it more difficult to make a name for yourself. The mechanics of a team match in COD at the highest level are more in depth than most if not all fighting games. Additionally, the fact that it's team oriented makes it somewhat reminiscent of professional sports. Simply put winning is more difficult, more rewarding and therefore warranting a bigger pop-off. I've played COD for quite a bit, I played Injustice and Mk9 as well. Also, don't kid yourself. Haggy (parasite) doesn't pop-off off like this on stream. Stream scrims are the fgc equivalent of casuals, they're rarely taken seriously.
