I don't believe all three together will have the expected results, especially the reward curve, in my opinion, increases the incentive to use voting bots to upvote your content. Using these bots is much more worthwhile especially for smaller quantities of votes.
I do support the curation change since it gives investors more control over their votes and is an incentive to vote organically. Nonetheless, it would also lead to higher concentrations of votes on fewer accounts.
I think the most promising change would be a separate downvote pool since that gives people more control over who (in their opinion) deserves rewards or not.
