I sometimes think this map should be talked about more.
The concept of a fully asymmetrical Arena map is interesting, and this map pulls it off well! I remember it being very well-balanced between the two teams, and the asymmetry combined with Arena's automatic team scrambling kept things a lot more interesting round-by-round compared with the average Arena map where you're doing the same thing over and over again.
Additionally, all the use of angled geometry and the highly detailed mining-industrial structures make this map reasonably pleasant to look at, although I think it could use some more micro-details and more expansive out-of-bounds detailing.
The reason why it DOESN'T have these things already is probably the result of it being a fairly hard layout to optimise.
