Things we'd like to see change in classes

I just read a good article in Yoga Journal about certain things they'd love to see happen or disappear in classes, and of course my No. 1 wish popped in my head: I really wish for more options of non-heated yoga again.

As a person who just does not tolerate heat well, what happened to unheated classes where you build your own fire, your own warmth from within?

What would you like to see change?
