Thanks for the thoughts!
Disproportionate earnings is actually not a big frustration of mine. I think for the most part people are being rewarded fairly and while there are some minnows that get overlooked, I think this will change over time.
The more concerning thing to me is when changes are made without full transparency (e.g. the payout being changed from 24 hrs to 12 hrs back to 24 hrs). There needs to be more transparency for all users when it comes to changes made in the protocol.
