Rune calculator for s8 https://www.mobafire.com/league-of-legends/rune-page-planner#&rune=Domination:4

S4 Mastery 9 + Runes 12 = 21 + 5% bonus AD.

S8 Runes Domination/Sorc = 54 bonus AD (+12 stat shards, +18 Eyeball Collection, + 24 Absolute Focus) Lets also not forget the 8 AD compensation buff all AD champions got in s8 Preseason bringing this total to +62 bonus AD.

S4 'Keystone' +3% damage increase S8 'Keystone' 30-180 + 0.4 AD + 0.25 AP bonus damage.

How exactly does Riot still claim there has been no damage creep over the years?
