Badlands is the only map I can think of where players can't actually pressure the point without completely committing their lives and dying. To pressure the point on badlands you need to walk into the tube where you are so easily juggled against the walls and 2 shot by a scout/soldier/demoman. Every other map has either: 2/3 directions from which you can pressure the concealed point (gullywash, snakewater) or an extremely open point where you can pressure it from any side, even above, without getting juggled or committing your life (process, sunshine, reckoner, granary_pro, metalworks).
Gullywash's last capture area is extremely similar to badlands in that it is very small, but completely different in that you can pressure the point from secret and water, and even soldiers can rocket jump in and out of the point at will. That's why gullywash is so successful and a very adored map by almost everyone. You can add an element of this to badlands by making 1 of 2 changes (and I would recommend making both): First, remove the back-side of the tube so that the point can be pressured from either side and players can move freely around, which also brings into play a large portion of the last that often goes ignored in the current meta (from my experience). Second, remove the glass above the point at the start of the tube so that soldiers can rocket jump in/out of the capture area, just like they can on gullywash.
Just a note, keep the area inside the tube where the lamp exists because I believe it adds some interesting plays for the attacking side's soldiers.
