I honestly want to see something similar to Hardpoint or old school COD HQ. The closet mode we have to that would be salvage, which is a solid 3v3 mode. I honestly think though an overall area where guardians would have to defend would be a great. While controlling the area you could have increased grenade and melee recharge rates. Or vise versa for the team having to breach the area. Do 60 second times for each base, 100-250 points per 5 seconds controlled. Kills in the base be worth 150 (plus heavy kills, super, head-shot, etc..) Have a 4 or 5 hill rotation for every map Heavy will drop once per game. set score limit to 20k or 25k. You'll have a lot of bodies converting to one small area so matches should go by fairly quickly. 10-15 minute match limits. The only other mode I could think of off the top of my head that could be coming back would be CTF. I also feel like an HQ type mode would be very fun to play. It would make random guardians to work together to hold a hill in theory.
