And as FistMarine said, we could always use more TA maps. I am guessing the lack of them is due to the fact that it must be purchased, although it could also have to do with elitism and the general hatred towards anything that is Team Arena. (not aimed at anyone in particular)
P.S. Nice work on the vortex portals, they look just like the real thing!
