It would be nice when two or more groups are working cooperatively to see the other group's members positions. This has probably been suggested but I couldn't find a post. My suggestion has two parts. First that group leaders be allowed to form small, maybe four or less, groups with a dedicated chat channel for tactics planning. Second, that we would see the members of the cooperative group(s) positions on the map in dimmed or different colored icons. I don't think they should be on the HUD or compass.
