Hextech Chests may have diminishing returns on skins
I have been getting more Champion Shards than Skin Shards, recently.
Out of ten boxes, 7 were champion shards and 1 ward skin, 2 champion skins.
This ratio has never been this bad for me in the past, but since I own quite a few skins already, I had thought to myself that there could be a diminishing returns system for the # of available skins left to win via Hextech Chest. It could include factors like skin price, skin release date, etc.
It just seems to me that I have never won a skin that was released recently unless I have purchased the chests during an event such as 2016's Snowdown Showdown (a very good event, imo). Chests were once very good to me in the past but now are not so good. Has there been changes that anyone else has noticed?
