Did some private testing and wasn't satisfied with the results, so now point E is more central to the middle grounds instead of on the map border. RED has more cover and access to health/ammo, while BLU loses a bit of cover. The big metal spawn door was also removed, and that really cleaned up navigation in the third BLU spawn.
Now the point is captured in 15 seconds by a Scout, with a 9 second cooldown before RED owns the point again. RED spawn waves are initially 10, while BLU is 6. Every time the point is captured, RED's spawn wave count goes down by -1; every other capture lowers RED's spawn wave count by -2, and BLU's by -1. This repeats in this order until RED spawns in 1, and BLU spawns in 4.
This was to beef up RED's defense the more BLU chose to be aggressive. This also makes it harder for BLU to defend E while RED can spam the point in counterattacking. Without this, BLU was able to park right on the point with absolutely no retaliation from RED... they'd die before they could reach the point and do any serious damage!
Yada yada, images will be updated soon enough, etc etc.
