I just don't get why they don't add a top 100 token that can be used for top 100 rewards and keep them on a vendor adding to it every season.

No FOMO and you can always get the rewards. It's basically PVP ultimate.

They did it with the augmented hellhound weapons to a degree but we need more. These tokens should be for top 100 only to have them be something to shoot for. The issue with trophy crystals is that you can get them at diamond thus they don't requires as much effort as staying in top 100 through the end of the season.

Also please god more uses for trophy crystals. Current crafting mats/stuff that sells on marketboard. I'm getting close to 99 stacks on the series and that should not be a thing.
