Iteratin' like a madman. I think the issue with the map was that attacking mid was ridiculously hard.
Added a one way drop down door into mid, and a ramp because my displacements are terribad.
A new route from spawn to mid, and an easier way onto the top of the bridge. Nobuilded the top of the building but it's a cheap fix.
Fixed the dumb crates that made getting to mid a hassle, replaced it with a ramp and added a ramp from the bottom floor too.
Added a ledge under the windows at intel to combat the massive fall damage and give a route back to spawn for defenders.
Changed to invade ctf! I think I'll make two versions of the map for testing purposes, though. Might build it into the map so it tries one of each mode in one test. Given the other changes I'd be interested to see how it works as regular ctf, too. Either way, it will be nice to really stress test the intel areas, they were sort of empty during the test.
Three small health kits at mid.
EDIT: Also changed the reflectivity of the dev textures because it was blinding originally.
Thanks to everyone who played! Big thanks to Randdalf who left a lot of useful feedback.
