CIRCULTION is a symmetrical map. at first glance you may think it is asylum or built from it. it is not its built from scratch, and obvious difference is the center of my map meets at 3 points so it has no line of sight straight through it. have a look!
Judging by the pictures, I can imagine you'll have some problems with framerate. I can't tell exactly what it is, but if its an active camo or a drop shield, you're going to want to remove it. I get the feeling the either floor of the middle structure is going to be pretty campy/easy to hold off, so giving the team in control either of those AA's is just a bad idea. Breaking the LoS from the top isn't exactly a new idea, seeing as the original Sanctuary and the current MLG version both sport the fixed LoS. This is still a good idea, but eliminating the base to base LoS down low, was not. This LoS is constantly used i both CTF and Slayer games to help make the areas in front of the bases more dangerous and to give teams a chance to stop flag runs.
Looks like the Halo 2 map, Sanctuary. The only thing that catches my eye (in a bad way) is the rocks bordering the map. They just look wrong from those angles you provided.
Well i wasnt trying to rebuild sanctuary or asylum, i was just saying it may look that way, i wasnt trying to replicate the gameplay of it either. but we did testing and there was no framerate, and its still has 5000 budget left to.
