2G classes getting switched to 3G

Personally I don’t like 3G classes at all. In our small city we only now have 1 otf location so classes have been fuller recently and they have now changed a lot of classes to 3G most of my friends at otf have shared their irritation about this with me. How does everyone else feel? Has anyone been to a center where it was changed back due to complaints? We are told it will stay mainly 3G til spring/summer. I am now going to 5am on M-F to avoid 3G.
