Transit is 12:13 A:H, and is far more balanced than Spacetracks- It'd take a lot of work to balance spacetracks out, rather than replacing Transit with Spacetracks, I'd love to see a "Transit Revisited" think what the Nexuiz/Xonotic community does with EVERY MAP EVER - the massive drops in FPS.
Things I'd like to see in a transit revisted would be:
1) Turn the lights down please?
2) More fps, without detracting from the overall feel of the map.
3) Fix the dumb blood stains which move when you get close/far away from them.
4) Rework the map, make the ledge base... Less appealing. Make the trains look like trains? Get rid of the ugly black "walls" replace them with blue force fields. Mix the map up a bit-- Maybe add the outside section? Keep the large size that I know and love.
Thermal, love the map, could use some fine tuning, there's quite a few glaring bugs: Lava, borked textures, etc- Karith, eh I've played it too much.
Nano: Meh.
ATCS(HD): See Nano.
Procyon: more plx.
Temple: Die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die, die.
ETC: Idk, we need more maps in general. Just nothing silly like rotcannon, or any "cannon" maps for that matter. Oh, and never... EVER, paint. I despise paint, all of them.
Too bad none of this is likely to happen in the near future, so far as map rebalancing/reworking is concerned anyways...
