I'm fine with chanting a lot if it arises naturally. A really live crowd can chant all the time and it adds to the show rather than detracting. I've been a part of those crowds and it's SO much fun. It just seems forced most of the time now, especially when it's a small crowd that knows it's being televised. Mostly it reinforces bad habits for more laid back shows.

Told this story before, but I was at an Evolve show recently. It was a small room that had a nice crowd that wasn't too rowdy. The problem is there were 3 dudes next to me who thought that every show needs to be like Full Sail. Only one of their chants took off (they were quite literally starting them every 5-10 seconds) and they couldn't get it through their heads that they were annoying everyone. They saw it as everyone else refusing to have fun.
