I don't mean to sound like a naysayer but I still see boxing (at the 3+ level) to be a niche. A fairly small one in the grand scheme of things.

Obviously we all enjoy it but most WoW players do not and will not.

There MIGHT be an opportunity here but I don't see it being lucrative enough to entice me. It would however be nice to get the five figures I have spent on my setup back somehow - but I am not exactly counting on it
