Runes / Crafting / uses

Hey guys, you really should find a late game use for the runes, maybe like Diablo 2 crafting. The added tiers feel great, but there should really be a special crafting with them so there's incentive to use them and not just STASH endless amounts, even if it's something minor, would be fun. Same feels like for support gems when u start hoarding endless amount of them... Feels like an underdeveloped system sometimes.
That's all.
