Just going to have to say I disagree with you from a business perspective. Riot is a company and companies don't stay afloat without money. If I had my way as a player, I'd ask Riot to normalize all champion costs. Every champion costs the exact same. Pick a number, I don't really care the number, but that's the number every champion costs for now on.
Doing this will stop these constant whine threads about how every new champion is 6300. If every champion is 6300 then there is nothing to complain about.
The game is free, and you can earn every champion by playing for them. It's a lot of time invested if you put absolutely no money into the game. But then again, if you put absolutely no money into the game, I could really care less what you think about pricing.
