This could be an interesting starting point for a broader discussion as we had a similar problem with HIVE witnesses... Those on the top are getting most of the rewards and the rest can barely pay (if they can) for the machines... The issues are what we are experiencing occasionally, unstable nodes, laggy HIVE front-ends, etc...
We should definitely implement more linear rewards and incentivize people to run nodes, and in this case, people don't even want to try as it will be just an additional cost... 😞
This would be great as I am a bottom witness for both HE and HIVE and I am glad I can pay for server.
