There should be a prosses for making proper firefight maps. These maps being made of parts of a push map don't work the obj are in weird places. Some of the maps are just a lil too messy with weird angles. I think you need to approach players who have a lot of experience on your firefight maps (like DGL and SEL players) and ask them what needs changing how balanced are the maps. Talk to people like penndawg, link, masser, vapor and zappatista. Long story short ya need to make really good maps for firefight as it is a damn fun good game-mode and could be the way to go. i personally really liked district and miss it. would like to chat bout good maps and wouldn't mind helping with the prosses of testing.
