I'm in, but are you sure about Kago?
The gameplay is very funneled, and it actually makes a lot of ppls framerate drop drastically when compared to other maps.
I know there are not many alternatives, and this is probably a dangerous statement for me to make, but if we're lucky we might be able to play the fixed version of Marshes. (Before you ask, no I don't know the release date!)
I'd actually be willing to have a look at some of the community-TC-maps, if that's what it takes...
