I'm glad I finally crossed the 1000 elo threshold before this change happened so I could take a screenshot to celebrate the milestone. Take a look at the difference:
Yay! Finally made it to 1000! Time to celebrate all that hard work paying off!
vs.

For unfathomable reasons, your UI people decided to remove the rating change summary from the endgame "You Won!" and "Lost" popup splash screens. That figure is literally the only thing I, and I'm guessing most people, care about at the end of a game. The Mistakes/Blunders/Missed Wins summary is fine I guess, but pointless, because it doesn't match up with a full Game Summary.
Instead, you buried the most important thing of all wayyyy down at the bottom of the screen under my profile, with a tiny little green or red +8/-8 that can barely be seen.
That needs to go back into the splash screen. It's the only useful piece of information on it.
