I loved the snowdown shop , only complaint would be ...

That while the skins (most of the time) on champions that we play, you did not check to see if we had skins on the champion, often times giving us 2 skins for the same champion. I have rank 5 mastery on Karma and Shen, and 4 on Kennen and Brand but barley no games on Soraka. My shop is as follows: Order of the Lotus Karma, Blood Moon Shen, Yellow Jacket Shen, Cyro Brand, Dr. Kennenand Dryad Soraka. As you can see, other then the Soraka who is completely out of place, all my offers for skins are on champions that I do play a lot. However, I already have skins for Karma, Kennen and Shen so 4 of my 6 skins are on champions that I already have skins, and I am not a fan of having more then 1 skin per champion. So again, I loved the Shop feature and would love to see it on other holidays, but next time I would appreciate if you guys checked if we already have skins for certain champions, and do not give us 2 skins for the same champion.
