Would it be possible to show item passive contributions in post match stats when hovering over them?

Also see stacking buffs like Kindred marks, Nasus stack, etc.

that actually makes sense please

Would be nice...

I posted a thread about tracking the on-hit damage had provided in its tool-tip. So we could know how much damage it provided in a match... got no comments and downvoted... bizarre.

It would be nice if you could see its on-hit damage contribution post game as well.

Possible? Yes. Will it happen? ...........

It very likely will as they have something similar (at least in-game, not sure whether also post-match) on PBE
