I think at the end of each group missions ( BP, BS, Hive S, etc) we should have a screen with all group players stats with number of bot kills, number of players kills, number of death mission time, etc.

yes

I could actually see this being part of a larger "group" panel under the PDA. Or somehow tied in with the "mission log" panel.
