So I have only actually been playing since just before the CC guys got into the game so all I have seen are is the current 3 maps in rotation and the 2 maps I casted during the draft on the private server.
what I think would be cool for public servers is the ability to break up maps. Especially for TDM and Stopwatch.
Example,
Bridge & White Chapel are broken up into 4 main objectives (maybe 3 for bridge alt I cannot remember)
having the ability to start White Chapel on objective 1, 2 or 3 and do either 2 or 3 of the objectives would basically much extend the map pool.
So you could jump in a stopwatch game and just have to complete objectives
1 & 2
1 & 2 & 3
1 & 2 & 3 & 4
2 & 3
2 & 3 & 4
3 & 4
The same system could also work with TDM but down to even a single objective area.
I would love to see the full size trainyard back in the game… saw a cast on it and it looked epic!
