now that we have more than 300 skins..

Riot can you please start put 4 skins in sales for rotation, instead of only 3? Like me a lot of people buy skins only when they are on sales. So the more skins we can find in sales, the more we will buys RP. I thinks that 4 skins is still a reasonable number for all the people that don't have much money, but still want to support this game and buy cool skins.
