I edited a bit for clarity, but I assure you that if you had read my post carefully you'dve gotten my point before hand.
I assure you I read your odious suggestions word for word.
What might be good though is to add a menu map like a lot of other games like OF:Dragon Rising, Fallout 3, Farcry, SWAT4, S.T.A.L.K.E.R VEGAS2 etc etc, have: a map you can open and look at which shows your current position and other terrain... maybe even the triangles for teammates too.
