Not Pwnuts but here's an answer. In theory, yes.

But, one issue that should be considered, and I think it has, is the people /tribes that have been with the game since it's beginning and playing under the existing system have managed to build up there tribes to max/ or close to max size. Do you change that system and risk alienating them? When is the right time to implement a change along these lines?

I think Xsyon has decided to wait on this issue until the game has evolved a bit more and there is a better balance of old -vs- new players to hash out a good compromise that works for a majority of players. I agree that for now that's probably the best way to go on this particular issue.
