Can we get back the old armor and magic resist values accessible with runes?

Back then we could have resistances values roughly equivalent to 40. Now we have 30 of each.

It would fix so many problems.

Lanes phases wouldn't be over at 10 minutes.

Marksmen would need more time to kill a target.

Mage supports are absolutely unmanageable. If you don't have a mage that can poke as a support as well you can't do anything. Zilean, Brand, Zyra and Xerath are absolute nightmare to deal with.

Every champion in the game wouldn't deal so much damages.

Fix this seriously, it's among the biggest problems of the game right now.
