Yep, HTC isn't interested in booting inactive players. I think that the percentage of folks who would spend more than 2 minutes trying to get around the "inactive" would be small, but its a non-issue since it isn't going change. ENY very rarely bothers me in game. Most of the stuff I fly or drive is rarely effected and when it is the stuff farther down the list is plenty of fun to use. Its is a source of frustration for some and although I don't agree with a lot of what other folks get frustrated at in AH, I want players to be happy and stay so we have stuff to shoot at.
I think with a little brainstorming there are alternatives to how ENY works that would accomplish side balancing and produce less whining.
