Its pretty open now. You just can go core to core.... otherwise they'll be too many shoot them as they come out of the coreI'd open up the top completely so flyers can get to the other side and attack AA from behind.
I still need to fix the hole and the messed up spawn point.
I think I want to remove LT and replace with the Vampire tank. I think replace badgers with GIIs. So the only lasers will be the King HH at the cores.
I will add some cover to 7, but I think the key to 7 will be getting your shield tank there.
