Pick em' Rewards

As some of you may know the pick em' rewards for the 2016 world championship is going on currently. While selecting my order of teams to win, I thought to myself, what was the grand prize if someone were to win? As I remember Championship riven was last years reward. I was very disappointed to find out that this years reward was all 3 ultimate skins. Yes I understand that these three skins are a 75 dollar value, but what if that person who wins already has these skins already, Do they earn nothing? I just don't find this to be a good reward even for someone with one of the ultimate skins already. The skins aren't that rare either because they can be purchased at any time and I do not see any significance in "being the winner" of the pick em' challenge of 2016.
