I don't know if someone has the same "problem" like me, but if you play support (or even some others roles), where there are active items, you can look ingame while hovering how much this items got you (i.e. Locket Shield, Redemption Heal, ...).
It's a fact, that there is a "Runes"-view in the post game lobby, where you can look how much your runes has done.
Now my idea: Please do this for the active items too. It's really annoying to do a quick look at the end of the game and remembering all values to analyze the game afterwards. I hope some of you will agree with me.
