Perhaps another change would be to an inflationary policy. A lot of economists think a steady inflation rate of 1% or 2% is good for the economy, to stop people hoarding coins and to encourage investment. Without getting into the argument of whether they are right to think that, a new coin with such a policy hardwired might attract a lot of support in some circles.
It might also attract miners, who would presumably continue to get a high block reward for mining, while keeping transaction fees low. In effect, the people who hold onto their coins would be subsidising, via inflation, the people who spend them. The low transaction fees would make the altcoin attractive to users and the high block rewards would make it attractive to miners, and the inflation would make it attractive to economists who believe that inflation is good provided it is low and predictable. Everyone wins.
