With the market being what it is and the lack of engagement, most of us already struggle - so losing a big chunk of author rewards would definitely hurt. How do we compensate? From curation rewards!? In that case, I'd be forced to forget about voting some of those who I know are not making much money, just as some of those currently supporting me would look to increased rewards. Votes would go to top-earners for better rewards, leaving minnows with a smaller percentage of a smaller payout! Hardly a recipe for increased user retention...
