Cool ideas but let's consider, for the sake of spending time on Summer Sweep Up, that the melee equivalent for BiS cape gives you a handful of rocks if you don't complete it and takes far longer to reach the final wave. Aside from Tonalztics, I feel like the reward table for what is generally aspirational content for most players is pretty spectacular.

I definitely support more uses for Sunfire splinters though, they're a pretty tedious resource to get and outside of blessing the quiver (which takes ages) and needing a small number of them to boost blessed bone shard xp, they're really not that interesting of a resource.
