Boxing is the only reason I still play this game.
I had quit, but saw a video by Ellay on WarcraftMovies.com, and that sparked an interest again.
I had two accounts, played with auto follow and two keyboards etc, for a few years prior to this.

I don't see them removing boxing from the game.
And about the only way to effectively kill it, would be to remove the ability to follow.
If that were the case, I'd likely sell my gold and accounts, and then look for a new game.
I've never done RMT's in warcraft, but supported myself for more then a year in EQ via a power leveling service - where they played their own toon and I played my six... effectively sold my time.
I'd rather continue to play the game, but if they were to remove the ability to do so, I'd get what I can out of it and then move on.
