the performance is indeed much better. these are the issues i still take with it, before i could say it's ready for inclusion, bold ones obligatory (and i'd really like to see it included in 1.5 as much as anyone):
-the alarm sound needs to be toned down a lot. add a max radius to it and set a volume, based on wherever it is intended to originate from. for those who play with no music at times it is very annoying to hear it across the entire map. also all the sounds in general may be a bit too loud, perhaps decrease their volume by 25% or so or move the entities or change their radius so the effect is lessened.
-some textures are scaled too small (one should be careful scaling anything to the 25% range over a large surface). namely the wicked tile floor colored red and blue in the center, and the grass texture. if you scale the tiles to 1 and darken them some and soften the glare it looks much better (bright team colors for bases don't go well with this map). the grass texture doesn't fit either, doesn't seem natural. mess with some vortex settings to make it look better. and add some autograss! (maybe paint it, like in ares).
-there needs to be a clear route to every affinity (flag, defend & control point, bomber ball spawn point) and weapon that only requires walking or a single jump (use of pushers or ladders works too). there are weapons and defend & control points that are too difficult to access (this does not apply for the rocket). the zappers for instance are far too high and out of reach without the use of fancy parkour moves.
-there are very few environment variables set whatsoever. you have room to be creative here, maybe it could benefit the map. there's sunlight entities, /skylight, /cloudlayer, /cloudscroll, /spinsky, /fog, even particles. i hear what sounds almost like a storm but there is nothing moving in this map, it's all dead. add some plant mapmodels? large water planes are what really decrease performance, doesn't mean there can't be any water at all.
-it needs more clipping in quite a few areas, and could use updated waypoints, but don't sweat this stuff, as there are many others who can add it.
-small thing, but it couldn't hurt to take a screenshot for the map image in a non-edit mode, so weapons aren't hanging out everywhere.
i try not to mention things relating to design decisions, because the design is very good and only lacks a little more accessibility for bots/n00bs. adding more pushers or a creative use of ladder material will help.
