Items:
(don't make AD specific)
Champions:
(fuck half of these designs that can't be healthy and meta at the same time, need better more consistent kits and playstyles, and the others are just outdated.)
Summoner Spells: Nothing really.
Runes: all of them, a revert back to a free version of old runes and masteries.
Objectives: Dragons (should go back to one, fuck whoever gets 3 infernals wins.)
The jungle: (should go back to 3 camps for level 3, smite buffs instead of jungle sustain, scuttle should lose importance besides river control instead of an XP and gold lead that gives a fuck ton of mana, basically revert back to season 5/6.)
Lanes: should hit 3 quicker off of first 2 waves instead of royally fucking the jungle role because "ganks before level 3".
