I feel as though this corner causes an abrupt stop to the flow of the map. Perhaps if the wall was opened (and the bottom portion became a ledge) it would help.
This spot screams for a railgun. I'm not too sure about what you would do to the other railgun if its spot in the map was replaced to here, but it's something to consider. I also don't like having two rocket launchers in the map, but that's just me. I haven't played with anyone, so I can't conclude whether or not two rocket launchers are beneficial.
Thanks for the suggestions. I think the swapping health/armor shards is a good idea, and others have suggested moving the railgun to a different location as well. That wall was originally there to help reduce a long lines of sight, however I may be able to work around it. Either way I think that that particular intersection is a little weird and needs some work. Good eye on the z-fighting.
