Hello again!
On point A something potentially concerning is that looking through the window on the orange building a sniper can watch the furthest entrance and half of the point the reason it could be a problem is people can get upto the roof and shoot down onto the same half of the point/another entrance. Which is why the sniper point can be powerful since the upper entrance through the window will likely be popular (although it does take a bit to get up) people wanting to fight people in the window also have to avoid going in the sightline of the sniper, blu in the windows can shoot into one entrance and the sniper will be watching the other. So red may have to go the other half of the room but blu has another entrance that they can go through to go over to there (with a little health pack they can take while they're there) and they can easily switch which direction they're attacking from or they can also flank with the lava drop route if they want. So red probably need a bit more help in point A.
I like the new route with the lava drop is quite powerful to blu at the moment as a way to flank A since blu have a height advantage going in and they are able to jump over the gap as any class whereas red have to go around, it also makes it so that red has to cover more of an area although there's a health pack that would make them want to be a bit more around the back anyway. But blu have to go through an uphill tunnel to get out which can make it easier to watch.
The bigger space between a-b has helped in the time to get from the points but it may be a bit too long of an stretch with not too much cover/elevated things to get through, a sniper on red could stay on the roof to the right/rightmost window and see all the points. I like that you can jump through the waterwall onto the other rocks as any class and the new route with the lava drop in it. So there possibly should be a bit more cover/it to be cut down a bit
I like the risky route to the back of B. I think b might be too difficult to defend as is, it's quite a small enclosed area you have where the point is and blu have lots of different routes to go.
Possibly a problem is over here:
You can easily shoot down onto the point/around the point from a height advantage and easily move to either the left, more forward which is also above or flank from the sign or go down.
Some of the possibilites for things to do are maybe even close off the windows entirely since blu already have 4 possibilites for ways to get in and they may have too many ways to attack from at the moment. And to make the room where the point is a bit bigger those are the main things I can think of.
The going through the waterfall thing is cool it's more of a problem with the waterfall itself in that if you're standing from the lake you can't see through the waterfall but from the otherside you can see through which is a bit of a problem.
And finally C the main thing is the spawns could be too powerful, you can stay around spawn and defend from 3 places albiet the right one is the weak it still contributes a bit, the main problem could be the other one, you can hang around the resupply cabinet going into either side to defend.
So the resupply could be moved more backwards. Also the whole spawn may need moving backwards since you are so close/in a good position to fight the point as soon as you're out of the big door.
Anyway that's about all, seems nice overall and it already looks like it could be a fun map, goodluck!
