I would definitely like to see more koth maps in the 6s map pool. This map has pretty good design so far.
I'm not a mapper, but I do play 6s.
The sniper sightlines are not too strong, which is good.
Some suggestions:
I think that maybe it should be a little more easy for scouts to get up on the high objects at mid. Without the Winger, I could only get up there with the Boston Basher. Maybe not though..
Going out through the main door to the control point, there is a group of rocks to the left. I would recommend somehow changing this so players don't get stuck back behind those rocks; as medic, it's quite difficult to get out.
Nextly, also to the left before the control point, there is that crate that leads up to that platform. I would recommend putting another crate or pipe or something there so that medics can climb up there.
Keep up the good work!
