No Limit to Chest Acquisition for S- Rank or Higher

It is no easy feat to get a S- Rank or higher in this game. After playing a champion and getting an S Rank I was confused on why I did not get a chest at the end of the match. When I looked it up I see a discussion that suggests you can only get 4 a season. If that is the case I find that to be just plain wrong on Riots behalf. People play your game because it is fun, and then you add the crafting to is, genius. However, I understand wanting to make money as this is a free game. But its not like people are getting S- or Higher Ranks every game. I do not think there should be a limit, and I say after all the dam money I have put into this game its nice that I can find ways to earn content. - Riot stop the greed if this is the case and take the dam limit off. - If there is no limit, give me my dam chest.
