Because mods severely alter the original gameplay that America's Army is known for. Same reason why you could report a server to Pragmatic to get it disabled. The game was built for realism and balanced gameplay. Mods throw that out the window. It's not about doing things because people whine, it's about taking the project in a direction that restores the classic AA that we all loved.
Understood Nate,but I think the majority of players don't mind mods now and than to mix up the game play...it's all about balance of game play.....Jonny has done a hell of a job,along with a few other admins to keep this game alive,and it's commended by the community!
