Skins tab in collection: put world championship skin groups together

Currently world championship skin groups are all over the place if u select filtering by sets. It would make more sense if esports skins groups to be clumped together.

How is it currently:

1. World championship
2. like 6 groups of other skins
3. Worlds champions 2011
4. World champions 2013
5. more of regular skins....
6. WC 2015

why not just make it

1. championship

2. challenger
3. WC2016
4. WC2015
5. WC2014 and so on....
