While I understand the reasoning behind this, and I laud your efforts in creating this.
I'll have to agree with Quickdraw's sentiment, at least partially.

People are unwilling to nerf themselves, but not because they're "better" than everybody else, but because it's not fun to lose an encounter because you've got a handicap.

Good players are good because of natural skill, not because they play all the time.
I've got 720 hours played, and I'm still mediocre/average skillwise.

Some people are just naturally good at video games, and there's nothing "unfair" about being better than other people.

Some people are bad because they're using less than stellar equipment as well.
Is it unfair that I'm running better hardware than someone, and am therefore able to react to situations faster than they can?

Well this mod may just add new challenges for all those pro players, so they don't get to bored sitting at the top of the scoreboard :P.(Saddly i'm not one of them)

Unfortunately, some people are unwilling to nerf themselves because they have significantly greater expertise in the game (no doubt by playing it during 97% of their time in their mother's basement) and like to dominate the game and ruin most chances of the opposing team winning, but it's a good concept and I'm sure some people are willing to do it to help the game be more fair.

Should've know Fred was here before I was.. Interesting idea, I'd like to spectate and see how it takes wind under its wings! :)

Sounds good. I will try this on my servers to see if there is any interest among the top players.

yes the names get changed to name ( xy% nerfed)

This in an interesting idea. Can the other players see the handicap?
