Only a bad player with fear of exposing their mediocrity and no grasp on the game would complain about including something that is present in EVERY other FPS out there.
In a game like this one where high points will reward you with heroes and other reinforcements, a good KD and a high win percentage will generally go hand-in-hand. With that being said, though, KD is actually a better estimation of skill in the sense that bad players can be carried by a great squad to achieve an incredibly good win ratio – but not an equally high KD. Yet the game is by definition about winning, which is why win ratio should have a bigger focus than KD, contrary to how you designed the predecessor's stats page, where KD was the visual center of attention.
I bought this game together with friends and we all played the hell out of the predecessor. I really, really loved playing this game, but the fact that you left out this fundamental aspect completely voids the experience of anything resembling meaning. Why would you do this? We all stopped playing because of it, and since then I have been checking back to see if you have finally realised the promise you made half a year ago. But no, nothing yet. What the **** is up with this?! I have honestly NEVER seen such an indefensible decision from a developer. Ever.
