Hey Riot, here's some ideas.

Half all damage in the game.

Get rid of the chat option since no one knows how to use it constructively.

Get a new balance team.

Bring back Morello.

Stop balancing the game via competitive play.

Stop making one thing over-ride all the rest.

Buff what is weak instead of nerfing what is strong.

Greg Street and Bradford Wenban are lacking IQ, make them go to school.

Learn not to drastically nerf shit to where it's unplayable.

Learn how to balance numbers in general.

Use the PBE for actual play testing before bringing it straight to the live servers.

Better yet, actually play test shit.

Stop with the "mobility is necessary". I can't even play immobile champions anymore.

Stop reworking champions to the point where their identity is changed completely.
