We all know what can be done
Riot is currently not able to do much due to Christmas break. Unfortunate for the game's state, but good for them. We can only wait until after January 1st - which they stated. Patch 8.1 should be a big change. I'm expecting a long list at least.
Anyways, it seems on the Dev Corner a lot of things are being noted. And the Gameplay boards has done great bringing up issues and solutions. However, there's one thing I feel needs to be said.
Riot, make a game-wide poll. When people log in, there should be a poll with radio buttons to get responses. "Do you like Rune Reforged?"
"Is the leveling system a lot more of a grind than the previous?" "Do you like the BE system?" "Do you like orange essence disenchant rates?" "Is there a huge deal with damage creep(explanation of damage creep in layman terms)?" "Which do you is the class with the most issues?" "Do you feel lethality is too strong?"
etc.
This would get a clear community-wide census on what everyone may want.
