idea for the ranked system rewards

as riot said in thier latest dev post. they are looking for new rewards for the ranked, when the season is still live.

i think that we should give some sort of ranked capsules for each division rank(might contain blue essence, keys, etc..) and a skin for each rank(better skins at higher ranks). each reward can be granted once to avoid abusing the ranked system. since ranks will be position-wise, a skin for the position you reached will be good if not great.
