The problem is you can get up on top of the wall over looking the ramp. So since the demos are essentially shooting blind and I've got a wide stretch to choose from, it's easy to avoid stickies. I'm sure it was designed that way to make defending easier, but it backfires very easily. There really needs to be a second straight path to the intel, their choices are charge uphill against a heavy or try and traverse the entire map to come in the other door. We held the ramp long enough for engineers to set up.
At that point there are 3-4 people that have that room held solid, leaving the rest of the team free to roam. Even if they charge an uber, the sentries were spread out- they'd be unlikely to clear me/darkea and both sentries in ten seconds. And frankly, with the room locked down and someone to open the one-way door, 3 caps doesn't take much longer than it takes to charge an uber.
