AUGMENT VS HEXTECH

Hello, i wanted to know what is the better chest to win champion shards, because on the augment caches i just see skins, rarely see a champ.

Thank you for your attention

Its random - would only buy chest if you need champions and skins

I have atm 10 Championshards with 2 rerolled shards so normal 16 shards and they useless for me :D Hope soon new Champ
