I've just played the map another time and I think that there's one main problem that affects the balance in favor of Allies:
There are two fences near the fuel dump and you can now build entirely only one of them.
However, this fence helps allies because it prevents axis to access the fuel dump quickly.
I think this fence actually advantages the Allies team and therefore I think Axis shouldn't be able to build it entirely. I think it's the only thing that prevents these changes to offer a real new fun version of fueldump!
Anyway, appart from that, you did amazing job MaTT! I like the idea of having an improved #ET version of the map
