Riot didn't increase damage, they lowered it. They hit scaling late game champs harder than ever.

Conclusion: The problem is NOT that there is too much damage, its because the runes are too weak now so many champs can't compete or fight other champs that have surperior kits(no counterplay) Removing damage sources from runes and items is a bad idea the game is literally a balance nightmare now. I mean if you nerf zhonyas won't zed's take advantage? Damage items are no different. Items and runes are part of having counterplay and are a part of many champs power to keep up with certain champs that snowball like crazy. Solution is to revert damages done to runes and items for AD and the champs will no longer have a power struggle against everything existent.

Electrocute best damage: 50 - 220(50% bonus AD) Now: 30 - 180(40% bonus AD)

This one is blatantly obvious. Dark Harvest 40 - 80(25% bonus AD) + 6 stacks for champion kills, large minions give 4, large monsters give 2 stacks. Speed: instant and has 300 sec window on 150 stacks.

Now: 20 - 60(25% bonus AD) + 5 stacks when attacking a champ under 50% hp Speed only happens under 50% hp which is not reliable. Note: so dark harvest basically can't be stacked efficiently anymore by csing and farming(master yi?) he now must constantly take risks for less potent dmg. You can afk farm for 20 min and you will prob have only 1 proc. this needs a revert 10000%

Sudden impact original: 10 lethality Now: 7 lethality

cheap shot: 15 - 40 Now: 8 - 40
