3 Teams or Reverse Game Modes
What if we had a game mode where you start at level 18 and slowly progress backwards? Farm gives slightly more gold but you also start leveling down a lot faster. It'd be interesting to see "OP" level 18 champions with starting items and level 1 champions with full builds in my opinion. But maybe the level down cap shouldn't be at 1. Maybe it should be at 6 so that everyone still has their ults. And I'm sure people have already suggested having some kind of triangular map where there are three teams vs. each other except you earn gold and levels faster.
and
would be op in the late game.
