There are no top level players who think lights are overpowered, because top level players can hit lights, they can counter-strafe, and they don't get out in the open vs multiples.
Knockdowns, in my opinion, are completely unnecessary. If they are added back in, it needs to come with significant buffs to lights, because even as they stand now with no knockdowns, they are becoming increasingly irrelevant at the competitive 8-man level due to bigs being actually so mobile (esp with JJs) and able to so easily crush them in any circumstance. Base-defense mediums are now able to make irrelevant the light's speed advantages when it comes to base capping and defending. Plop a light-killing medium near base, and you don't have to worry about base defense.
I feel that most of the people wanting nerfs for lights without corresponding buffs are actually just bad players who can't aim or hit a light for crap, but in their world, lights are "God-mode unhittable broken."
EDIT: Removed part about public-Elo, even though I think it would be useful here. Having leagues (bronze, silver, gold, etc) would be just as good,.
