Resolve post game rune information

I'm a top player who mains Poppy, so every time my role is to get as tanky as possible and be able to absord the highest amount of damange.

For the runes selection I usually go with Aftershock and Shield bash. The only problem is that I don't know how good they actually are compared to the other runes of that because the post game data is useless. The Resolve page is mostly chosen by big top tanks that want to go through hell and come back alive, we don't care about the miser amount of damage that aftershock or shield bash can deal. We want to know how much damage they are able to absord while active, so as to determine if they are better than Grasp of the undying or more useful than font of life.

Especially for aftershock, I want to know exactly of much damage is mitigated in those starting 2.5 seconds after my E throws me into the enemy formation.
