Why not just make the missions you pick up auto repeatable without having to go back to the citycom over over. At least this way you're constantly killing/looting and less running and looking for the actual mission to do again. I just find it boring as sin to go to the city com, click on your faction, click on the difficulty and then look for the mission you are trying to do. Specially the kill missions, seems like we are doing more running than doing killing lol.

For example, i'm doing the Launcher Cyclop kill mission at Military Base. You pick up the mission at the base, run to the bunker, kill 5 of them (which probably takes 1-2 minutes). then run back to the base to pick up the mission again. Why not just have the missions just recycle after you complete it? Rather spend my short time killing trying to level instead of running back and forth over and over lol.
