Here's why: we now have six different colored archon shards.
There is a shard hex ephemera which can show off your shards visually which is fine, but I'd like a more elegant understated way to display them like:
Five gems on your right hand, each one corresponding to the shards you have on, doesn't have to be flashy or showy, just an elegant way to wear your achievement, and a subtle nod to the mad titan himself.
And I don't mean like a whole glove, just the gems in their spot on a warframes hand, one for each knuckle.
