Played it tonight in 6v6, it was really fun. Everyone loved the theme, and the map seems very balanced and well designed. We played 2 rounds; went A 1st, then B 1st for the 2nd round. After trying both strategies, A & B feel
almost equally defendable.
B might have a slight edge due to the height advantage above the cap. It seems a little like A gives BLU height advantage (after they get pushed back a bit), and B gives RED the height. However, its not nearly as clear cut of a decision as Gravelpit, where you ALWAYS go A 1st. While B does give RED the height, you never feel safe while defending, which is exactly what you want when making a balanced A/D map. There are long sniper lanes but equal cover, and several different paths and areas to attack from. I also though the HP and ammo placement was great, having the big ammo and HP out in the open in the sniper lane makes it a risky trip, which is good.
I don't have too much to say about A other than suggesting adding a medium HP somewhere. It would be nice to have for the combo to fall back on after they lose the rock area. Having the small ones around is good, but I think 1 medium HP would help RED. (sorry if there IS one and I just didn't see it) Also there was some comments about the roofs, maybe take a look at that yourself, I wasn't completely sure what they meant.
It looks like you did a good job with the paths to and from C. There's lots of ways to get to C, but you'll see in the demo we didn't spend too much time attacking or defending C. (I think this was just the teams, not an issue with the map) We liked it best coming from A into C, there was sufficient ammo/HP and it just flowed nicely. This is all based of of 2 rounds, so keep that in mind.
Overall I think its a solid map and we'll definitely be putting this into our PUG rotation. I recomend watching both demo's, just to see if the other team's games played out differently than ours. I hope this helps, I'll post more as we play more matches on it.
