Rise and Fall of Damage Creep

I feel like everyone glosses over the timeline of damage creep. Damage creep first became a problem because marksmen were killing squishies with 1-2 aa, then mages were 1 comboing squishies without poking them down, the fighters were 1 comboingsquishies without trading first to lower their health, so then assassins were buffed up so they could 1 shot those marksmen. Now that Riot is trying to lower marksmen upfront damage and the rework to people are complaining about assassins insta killing. Right now we are on the down curve of damage, but Riot did it wrong instead of nerfing assassin and marksmen damage at the same time they only lowered marksmen so then assassins roamed free. What needs to happen is that assassin, fighters, mages and marksmen all need their overall damage lowered and to do it closely together time wise.
