What I like about this is that it fixes a lot of problems with the classic server.
Lag for catching and running is no longer a problem, neither are hitboxes. It's harder to be illegal now because of building.
It looks a lot better, more map possibilities, the only problem I think exists currently is the fact that you can keep all your items after the round ends. This allows people to farm resources out of the maps, get in a safe place, and then smelt it all and become nearly invincible; especially in the face of new players.
I'd be all over making this permanent.
