Don't get me wrong, I doubt I'm gonna even play this "New" Gamemode as I don't want to sit through 50 waves of brain dead enemies, but to point out why the hell are you using closed off PVP maps and not the open gambit ones? With the Gambit maps you have one central location you could defend replacing the mote bank and three separate wave locations to spawn enemies in from and as the waves escalate could activate all three spawns so you're being attacked from all three sides. Not to mention the more openness of the areas making weapon choice more versatile rather than these closed off narrow spaces.
