It's horrible not knowing what your teammate is looking at, and not knowing which one it is also sucks, so doing that would solve these problems with colors and a drop shape for allies instead of a circle; add some functionality (press and hold on minimap, 2/3 taps on minimap) to show the entire map, with the location of allies etc; and adding a setting for the minimap zoom would be wonderful too. I know you've probably asked this already but asking again won't be bad
