The quality of this game is relative to you. For example, a hundred and one new, original servers would not improve this game at all for me. I join about three servers:
1) Slicksilver555's Server -- Pseudofreebuild, mostly just for chatting and jumping around.
2) Dotdotcircle's Zen -- Dotdotcircle builds while we jump around on his build and chat.
3) Centhra's Dueling Whitelist-Only -- Private server where we work on revamping Dueling while bitching about how Skill4Life is taking forever with the lobby. Jump around and chat.
Clearly, for me, this game is a glorified chatroom. That's what it is for a lot of people, and we don't mind the 'unoriginal' servers because as long as they don't break the chat feature they don't add anything to the game for us. I don't think I've joined a TDM in a year. If I have, I jumped around and got killed by other players who were playing while I chatted. This game is still interesting to me because as long as I have friends that play I have all of the original content I need.
It's getting a bit long and ranty now so I'll summarize: it's your fault that the game is boring, not the server hosts. If there isn't anything keeping you here, then leave.
