There should be a counter on how many different skins you encountered in the rift !

Id would be really fun if you knew how man different skins out of the hundreds available you saw ingame...

Maybe even a counter on your Summoner page ? Could be: You saw 121/~700 (how many there are at the moment) or jsut a simple number.

There could be rewards like 1 key and chest for every 100 you witnessed...

Im sure it wouldnt hurt your sales either riot !
