I'd think Spiral Command would have a heart attack if they saw how much mineral profit they lost to Knights' pets with the latest update. Not to mention the fact that the dungeons are turning almost completely green & blue. I think it would make sense both story-wise and game-wise if pet food was made with shards instead, we've got thousands of those. This way, people will go back to getting as much minerals as they can rather than only choosing the ones pets eat.
Thoughts?
I think this idea is ok and it would be useful because Light, Dark and Red are the most common shards. I have 1049 light shards for crying out loud!
