It's the same in ALL game modes. The lag since patch it sometimes unplayable. It's too late for dedicated servers that would require a full rewrite. But they could sort out the way their P2P works. Warframe uses P2P and I never suffer any lag. They do it by region and ping. As much as I love playing with the American friends I have made (I'm in England) Bunglevisions current networking system sometimes makes that rather large ocean seem like a lightyear across.
