Finally had the chance to take this map for a spin last night. I did find a fair few things about it that ain't up to the standards I want it to be. While I still strongly believe the map has a good base to be great a few more edits is needed to change the flow and spawns of the map.
It will be a fair amount of pictures, but I think it's easier to explain in pictures so I will use them instead of a wall of text.
So here we go:
This spawn was way to easy to abuse from low point camping on the armor, so I suggest moving it further in to take away that possibility.
A railing along the red line to block sight even more towards the spawn. With a railing I think there is space for another spawn there also. Will be a fair amount of spawns in a tight space of the map with the stairs close by, but since it's possible to go low, lava and via the teleport to high I don't think it's a bad spawn position.
It felt to easy to keep holding low from the armor spot, so I suggest adding a "punish" spawn, I prefer the lower position in the picture. To punish anyone standing on armor from having a to easy time to hold the spawn. Again through the teleporter it's possible to reach lava and top making the spawn possible. (ONLY ADD ONE OF THE SUGGESTIONS!)
Belt was way out of position and rarely bothered with unless someone had the amp. That's not good! So I suggest moving belt up and put it either very close to the edge (yellow circle) or make some sort of extension for the belt like a small round part sticking out (blue circle). That will force the lava player away from the point and into a position where it's possible to be boosted down, all for the good.
The red circle and the arrow is a suggestion for a boost pad "shooting" you over the gap. This need to be directed, so no matter how you get on it the direction you get launched is the same. So it's not possible to use it for reaching amp. This will make going for top possible and don't make being at this side a death punishment for lava players.
With the addition of belt easy to control for lava this armor is not needed, to much armor in one place else and the map already has a armor. So instead of the armor I suggest moving the health pack in. Possible to add another ammo pack in the corner where health pack now is.
The line of vials could be clumped together, it took a bit to long time picking those up when they where so spread out. Even possible to put the towards one of the walls if wanted, as long as they are very close to each other it should be fine.
I think this spawn is great and could become two spawns close one pointing each way.
To force the top guy to play more inside the top room and not interfere to much with where the amp is unless amp is up one or both of those spawns could be added (most likely only one). So it's possible to spawn inside the room if the top guy walks to far from his spot. Not 100% sure which spawn I like best, but I think the lowest one.
One of the major problems was the amount of people around the area where the red circle is. So I suggest moving the end point of the teleporter further out so it's where the yellow circle is instead. Should make it fast to dodge on the launcher or dodge around the corners if your playing low. Making the spawn close to the teleporter useful for low also. Could with the moved teleporter be possible to add the spawn back at the red circle, but for the moment I would hold off on that.
This spawn and this teleporter was at least for me a very frequent use, since the spawn I got a big amount of times. I still think it's a okay spawn, but the teleporters needs to be "fixed". So the one in the picture should be moved so you end where I showed in last picture. It's should also be added another teleporter either opposite of the current one so you either dodge left or right depending on which one you want to take. Or it can be made on the opposite side of the "room". This teleporter should end up at the same position the one at low point does. This should open up and make it more variety to lava and top point where you attack from. Altering the flow of the map and releasing pressure from the top part around where amp boost is possible from.
Again to put more pressure on the guy playing low. Either split the spawn so it's two one at each side or add one further towards the low point. Since going through low teleporter is a possible route for both lava and top.
I hope you stuck with me and I wan't to hear what people think about my suggestions and if anyone else has other suggestions.
