I managed to fix a few things with this next version. It still might not play well but it should be better.
ctf_banja_a2a has changes such as:
-Removed fences breaking up playerspace
-Map shouldn't be as dark now
-Adjusted health locations
-There is now more health and ammo across the map, especially at mid
-Made mid smaller
-Shortened map length by 800 units (woah!!)
-There are now more obvious signs
-Made prop staircase outside spawn a prop ramp
-Put door next to right spawn exit to accompany the prop route
-Secret jump
-Removed door in short building, readjusted doors inside that building
-Changed placement of light props to avoid players hitting their heads on them
-Moved spawn pipes to do the same (for some reason you don't hit them in TF2C, but you to in TF2. Weird
-Shortened the depth of the underground water dropdown
-Widened main entrance into intelligence yard
-Removed spawn exit yard, added barriers to fences to indicate map boundaries (but I forgot on the other fences, rip)
-I did some things I forgot
-something something jimijam
Keep in mind that even with all of these changes the map is still pretty similar to A1. But it should at least play better.
