Well, I told you all in the V2 thread for this map that I was working on V3, and that V3 would be very different, and guess what? I fulfilled my promise! This was very hard and took very long to make (20 hours total, which means the making of this map has taken 45 hours), but this result was worth it. I changed almost the entire map in my goal to make the diagonal setup as good as possible for MLG. Here's the changes:

^Blue Base and Red Base after the changes

The bases were the first things on this map that I redid. They look much different now than they used to be. The first step I took in changing them was ripping apart almost the entire base and reformatting it for more cover and more teamwork to hold it down and to attack it. The most noticeable change that I made was adding the two towers to each base, which provide more gunfire cover and a place to put base markers, but make you more susceptible to being killed by or flushed out by a good grenade thrower. I also merged fence walls into the top of each tunnel, making it a smooth transition from one to the next. In addition to that, I extended the front platform back aways by adding an interlocked bridge. I deleted the floating bridge and box to make room for this. The two final changes I made to this base were the additions of two merged window panels two the front platform as well as a geomerged box inside the base with which to jump up to the front platform.

^The two corners, which give a slight peek at the new floor and the smoother walkways.

The next changes I made were to the corners and the walkways. This turned into a hell that took me more than 5 hours, but the end result was truly worth it. First, I moved everything over to allow for a smooth and perfectly connected bridging. Next, I straightened out each walkway, making very little bumps in between each bridge. The last change was to the cover on the long walkways, which were separated and in some cases, changed (double walls turned into upside-down L corner walls).

^Like the new center of the map?

The very last changes that I made to the map were with the center, the floor, and the weapon and respawn points. I deleted everything off the floor, the center platform, and each and every weapon and respawn point on the map (with the exception of a BR that fell through the floor and didn't delete itself). The center I moved to the EXACT CENTER of the two bases, allowing each team an equal oppurtunity to get to the middle mauler. I then deleted and moved around the floor cover to fit with the new map format. Lastly, I made respawn points and weapon points more evenly distributed about the map. I suggest downloading this if you're interested and rating it on its discussion page in the H3 forums.
