Some feedback
I like the concept of the side area in lobby (where the stacks of planks are), I just wish it had more space and was more interesting fighting in.
The hole on the roof on middle is unnecessary and I kept falling through it unintentionally while fighting on mid. There's also is no area to fight behind the house, which makes it very chokey. Maybe make so the roof is only slanted one way so you can't use it as a hiding spot.
Second spire is pretty well designed in terms of fun in fights, but there needs to be more visibility. Fights are really chaotic because there is no way to see what's happening in fights because the spire is huge and blocks all vision.
I like the flow of the map, except for how uninteresting the fighting areas themselves are. Every fight is pretty much straight forward dm and you can't really use the map to your advantage in a lot of areas. The sniper sightlines are also too strong on a lot of places. Make it so good sightlines are easily spammable or makes the sniper take a risk getting to.
Make it viable to run the right flank route to mid. It would make for more interesting mids if you could go different routes to mid and not have everyone go through the choke.
This maps looks promising and I would like to see it tested in cups soon enough.
