I completely agree with this as well. With the current system, the curators won't bother to vote a post if the reward is already over 1$. Even though it is a well written epic post. I would love to see this implemented instead of having conversations about removing reward pools. The current voting system has only created many snipers who rush to vote the posts with their big sniping trail in the 3 minute mark.
Even if someone comes up with a plan to change the curation to flat, I don't think it would be implemented because there are many snipers in the top 20 witnesses. 😉
