Indeed, it requires some love for both factions (and I mean BOTH factions).
Whole gimmick with gates that need to be open is simply stupid. Benos WILL meta-protect those codes/whatever, because they can freely use tunnels (even the biggest benos, which is stupid).
Train Stations will probably be meta-trapped for sure too.
What is the point of low temperature there? It's only drawback for marines in one bio-dome, so it requires coifs just because it's there.
Are mechs still even in code? I've heard that there is enough materials to build one. I can only imagine my dream come true of benos finally crying so hard, that they melt the floor of Corsat and vent the whole thing.
