About the shit talk on stage, the only you could say is a little far is the coach inbetween maps, but IMO I'd much rather people be yelling, standing up, calling people out and pointing vs super professional 0 reactions just nice job boys. its way more entertaining and adds more depth to the matches. obviously dont take it too far, getting personal etc. but I dont think thats been a problem at all
Edit: also if you are someone who gets mad at it, why? is it unprofessional, do only teams that talk deserve to do it, some other reason
