Ok, so I was about to make this post before I realized your map was running in the imp, so keep in mind when I took these screenshots, it was before I had played a2.
Feedback for each picture will be posted above it.
Ok, so this first area really throws me for a loop. On defense, I really have no idea where I should be trying to hold. Most Payload maps start with some kind of height advantage for the defending team. It's fine that it's different, it just makes me unsure of the best place to defend from. Since I wasn't sure, I went Sniper since the area is pretty open and has decent enough sightlines.
On offense, I really didn't like using the main door. I felt blind going out and very unsafe. I think putting the main door where I suggested here might work better? Not sure on this one, all I know is I do not
like using that main door.
These crates are such a tease. The only class that can get up there is Scout and he doesn't even need the shorter crate. Either take away the smaller crate or make it possible for other classes to use (spigot prop?)
Pretty good Sniper sightline. Has the small health pack behind too, which makes it better. You can get flanked pretty easily, but if your team is holding forward, it's really
good. I was able to get off a lot of shots here and I'm not sure the attacking team can see.
Seems kind of unnecessary. You already have the one ramp leading up there, this space just goes unused. It's not really a big deal though.
All these doors seemed like a little much, but it actually played better than expected. It does seem like there are a lot of options though and the tracks don't really seem like the main route.
This is a picture that is kind of irrelevant after the imp. Just by looking, I thought this would be the best sentry spot. Seems like people found some other good ones. The finale doesn't seem very finale-ish. It seems like two spawn doors and then a flat area. Once Blu gets to the flat area, it's pretty much game over. I think some height advantage for Red (or height difference in general) here would really make the area more interesting and finale-ish.
Overall, I really enjoyed the map. I feel like there are a few powerful Sniper sightlines, but that's just Payload. Every Payload map has them. I had a lot of fun playing this map and am looking forward to seeing how it progresses!
If you aren't sure what I mean with anything or would like me to explain further, just let me know!
