1) Lockdown Toggle
Probably thought of before, but it would be nice to set up a lockdown game where there was an option to enter a UV alowed or UV not allowed arena. That way, if you entered UV allowed, people would play lockdown in there as they do today. But UV not allowed allows players (both with and without UVs) to be on the same playing field. It would just disable any bonuses from UVs, and act as though they were wearing plain armor.
Better yet, (this was definitely suggested before), custom LD lobbies. Guns only, bombs only, swords onoy, no trinkets, Only recon class, any other classification. Basically like halo multiplayer customization.
ALSO NEEDS DEATHMATCH
Hmm... Deathmatch of some sort would be nice. I like the idea of UV LD but there would some OP gear there then.
