I think I'll let these images do most of the talking on this one:
Mid was reworked a shit ton, the main corridor to Mid was raised to make ramps less steep and to make it safer to traverse by the attacking team, and some non dev textures were added just for kicks.
And a few misc changes as well:
-Changed and added some health packs
-Fixed a glitchy areaportal
-Untinted the windows at the spawns
