Okay, after checking out the latest version, I have to take back some things that I said, but not others.
First and foremost, visually, it's gorgeous. The best it's looked by far. I was stunned by the amount of detail in some locations. However, there were a few minor visual glitches I noticed.
Now, on to the final two cap areas, which were my main focus for concern. The final cap is just fine. Whatever problems I may have had, it works perfectly fine now, as battle flow is focused into the upper area, as you intended. No changes required there.
However, the penultimate cap remains a bit of a problem. When leaving the spawn, you walk this way.
Now, whether you're new to the map or know it by heart, where is your eye automatically drawn to? The open area or the obscured stairwell that's covered by some kind of cabinet? The former, obviously. And that's still a bit of an issue; while players can have the choice between the two spawn exits, they should be predominantly using the stairwell, since it gets you to high ground faster, which is where you want to be when fighting off BLU, not on the low ground where you're susceptible to oncoming fire. You either need to remove that cabinet and make the path to the stairwell far more obvious, or just have RED spawn facing directly this way.
And going up this stairwell, there is still an issue with the sniper deck that it leads to.
Why is this grating here? I'm serious; never would I actually WANT to fall down there, and I found myself more often than not slipping down the hole, shouting obscenities to myself, and then making the long way back up to the deck. As for BLU, why would you want them down in that area in the first place? They should be pushing the cart, not spawncamping RED. It's an annoyance to both sides.
There's also the matter of BLU access to this deck. The only way up here are those tiny barrels on the left, and I found them to be really tricky to climb. If you want that to be an access point, then perhaps have them jut out more so that it's easier for BLU to climb them. And there has to be SOME way of BLU getting up here, otherwise Snipers are at way too much of an advantage to camp up there and not be attacked.
Now, looking at the final cap, I was reminded of something. RED is forced to defend the area from above, not below. That's good; that's how the map was intended. However, that begs the question: why does this area still need to exist?
I'm dead serious when I say that this area should not be open to both classes, and should be an extension of RED's spawn room. Why? Well, for starters why would RED need open space down there? To build a sentry? Seeing how the sentry would be defending the final cap, and RED can't go through that door during the final cap, that makes it a moot point. What about BLU? Do they have any business going down there? Well, no. All that's down there is an access point to get to the upper area where the last cap was, which is useless at that point, and a long-winded way to get to the house above the final cap, which can just be accessed by taking the upper catwalk.
If you just botch this whole area, it'll fix all the problems that I mentioned. Convert the area so that it leads directly to the stairwell that's not being used now. It'll give RED a better attacking point, and it'll make use of what's otherwise dead space. I'm sorry I keep harping on this, but I can't stress enough how this area needs to be fixed, seeing how it's the only thing left wrong with the map.
