It might be an OK idea on a server that isnt our main one... but people mostly come to play the game against friends in a server they love... not kill a bunch of bots that are moveing at half speed... plus, the codeing on MY part would be tremendous... modding all those bots and stuff. But your certainly not the first people to think about a mod like that for this game...
Oh, and please find the topic in the Maps & Mods board called "Add/Remove Mods" Found
Here and post further suggestions there, rather than makeing a bunch of new topics that will be quickly locked.
