I strongly believe one tweak would solve this. A free upvote to reverse downvotes. I talk about it here @theycallmedan/proof-of-brain-theory-and-further-optimization

I reversed some of the damage from ura-soul, but in doing so I also hurt my curation rewards. No big deal to me, but a big deal to plenty and enough to make it so most shy away and or can't do it on a consistent basis without diluting themselves in the long run. I will revisit this and try to push for a community vote on it.
