Player profile/stats page doesn't even display the Win / Loss ratio

@Adamonic That and I can fully imagine that an overall W/L ratio has so little to do with a single soldier's statistics that it is essentially meaningless. I've been with a full squad doing PTFO and leading both teams in terms of points, with assists, revives, captures, etc, but if the rest of your team is off with a thumb up their butt doing whatever, then it's going to be an L most likely.
