Spawnpoint placement is super important on any map, and i notice that yours are a bit inconsistent in the canyon mountains. Here's a guide i sketched up on the subject: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3004200610

The flags similar to "Emplacements" are very treacherous with their spawns; there is always a high chance that someone pops in directly in front of of behind an attacker, which is highly unfair. But the sawmill flag comes very close to having an "ideal" spawnpoint and attack route layout (according to my preferences, at least).

If you can master the process of shaping flag zones so that nobody ever pops up in a bad or unfair spot, that will arguably have the biggest difference on players' experiences.

BTW, i think i may have already posted this link on another map of yours, sorry if you've already seen it.
