Nice to see they adding crosshair customization, I suggest you have per weapon/class/global crosshair setting and allow users to import a alpha crosshair image file
ALSO:
Better threading affinity spread (keep threads off the core that has the high load thread)
Allow people to extract the game files from the upk files, disable compiled textures compression, disable ram cache area compression, add memory usage profiles that support PCs with more than 4gb of ram
Always sprint option,Hold to crouch,hold to walk mode
Port backup to the current mission area if they join midmatch from the other side of the map
Better spawns
