Overall I think you did a really good job with the map so far. I could definitely see this being more popular than some of last seasons maps with a few tweaks and adjustments. I decided to name your points temporarily just to make it easier to talk about them.
Ramps: 1v1 Point?
Stats:1 - 150 Belt (Far)
1 - 100 Armor (Close)
1 - 50 Armor (Close)
2 - Health Packs (Close)
3 - Vials (Close)
1 - Health Pack (Far)
6 - Vials (Far)
Clouds: 2v2 point for when amp is coming up, one guy stacking and floating in preparation?
Extra guy can aid Ramps CP depending on how fast enemies return
Stats:1 - KEG (Med)
2 - 100 Armor (Close)
2 - Health Packs (Close)
3 - Vials (Close)
6 - Vials (Med)
Amp & KEG - Under CP
Many more things (Far)
Bridge: 1v1 Point?
Stats:1 - 150 Belt (Far)
1 - 100 Armor (Far)
1 - Health Pack (Close)
3 - Vials (Close)
Likes:-Stayed true to your style, people will know this is a windigo map
-Good interactions between multiple CPs fighting over powerups
-Multiple ways to boost to amp (hoping the pad boost is only moderately difficult), Bridge CP can move to boost if needed
Dislikes:-Could be hard to shut down amps with multiple armors and a KEG in close proximity, as well as many health packs and vials grouped up in center of map
-I realize this is a WIP, but I think there could be a few more landmarks to help players navigate and learn the map faster
-Bridge CP doesn't have much going for it, the 3 vials it has are dangerous to grab, maybe add pads and/or another set of vials
Not too sure what to think about the spawns until I actually get into a game to test. This version would have been ready to test if you named the CP's and had the powerups configured correctly imo. Don't forget to set the KEGs to 200 Health and Amp's Charge to 15000. Looking forward to next version.
