Rather than re-release LAST YEAR'S skins, you should have released another past year's skins. I really wanted Snow Bunny Nidalee or Candy Cane Miss Fortune.
I bought a couple of the 2011 skins because I liked them and figured they would at the very least be in the vault another year or so, if at all. It irks me to feel like I was "cheated" because you just offer them up again this year while 2009 and 2010 continues to maintain their uniqueness by being locked in the vault still.
Feels like you just reward the "older players" for their monetary contribution with skins which are now unattainable and then the "newer players" are duped into feeling their purchases are similar but you go and make them available again.
