I really don't like how the River Compendium effects were done this past compendium. I had 60-100 Vials that went unused because
1. The time period allowed wasn't enough to use all these cool river cosmetics
2. The cosmetic required you to place the item in your inventory taking up space for an item that you actually need to play the game.

Really hope this doesn't fall on deaf ears. A lot of my friends got 1000+ compendiums and complained that they never got to use the river effects cause it wasn't worth wasting a slot for. Next season make it an action item like the snowball, kindler kits, or coal.
