To be honest, I think a wipe and a do-over with a more focused mod (smaller map, more bottlenecks for interaction, less junk) would be the best thing for the game. It would be a lot more fun.
But some people see computer games as "achievements", and they would really strongly dislike to lose all their precious stuff they fancy themselves having "worked" so hard for. People would ragequit, and under normal circumstances that would be fine, as the majority would probably come back if the servers were still fully populated and they could see people having a lot of fun after a server wipe. But that's not the case, the server would take too big a hit is my guess.
tl;dr: A wipe would be excellent for the game, but the community wouldn't be able to cope with it at this point.
