Massive amount of feedback + sightlines incoming

I really hated dealing with this sentry spot, it has a pretty clear overlook of the point and its hard to sticky spam this area because enemies will usually flood around this spot. My thoughts would be just to remove the little house behind this wall, but keep this wall here.

most annoying displacement in the world because somebody held down left click for too long. I found I can actually slide off this thing.

This is also annoying because its not clipped, I have to jump up it most of the time because I just slide off of the step.

I thought this sniper spot was too good. You can easily headshot anyone coming straight out of spawn, and most of the time, your team has your back so you don't have to worry about spies so much.

You can easily block off an area, and shoot through the window on the other side to lock down enemies.

When I wanted to get around the point via the under area, I noticed the train + the blocker stopped me from doing that. Adding a little space over on the left could help scouts so much.

Tasty sightline over the point, you can easily headshot engineers here.

I really noticed that when the attackers wanted to take the control point, their only option was to take to the upper area near the control point. The bridge really allowed players to do that more easily, thus making this point much harder to defend.

Putting a resupply cabinet down here would really help, sometimes when I'm on fire I come down to this area and realize theres nothing here except brushes and props.

I noticed soldiers LOVE this rock area over the point. You can easily spam down on defenders and quickly retreat back to your team. Maybe you should add a ramp in this back area but make it harder to attack somehow.

Brushes are overlapping here.

This is a massive "I can camp enemies" type of sightline. This sightline literally reaches from blu's spawn to red's forward spawn on stage 2. I really don't want to camp the enemy more than I have to.

Another really powerful sightline here, I can see anyone trying to take that medkit, and anyone who does will get slammed with a bullet to the face.

I didn't really see any point of this dropdown, unless its to escape all those pyros or heavies. I went into here one time thinking there were stairs I could go up.
Thats all the feedback I have as of right now. I'm really tired and I'm going to bed. I'll provide more feedback if I find anymore issues. As of right now its really cool, and I can't wait for this map to be realased along with the update. Good luck!
