Multiple posts already here but the recent shop just proves it.

No new collection after the Magepunk 2.0 collection so the Champions bundle is at the top.

If Riot doesn't want to be pressured by adding new skins every 2 weeks, they should improve their shop already. They're just adding more skins to the loot pool therefore making the percentage of the skins appearing in the shop even worse. ( Except the bad skins or the skins on the guns that people almost never use like Odin and Frenzy or the bad collections like the Ego, Convex, and the Rush collections. I know what you're up to Riot )
