And that's way changings in basics of Nxt shouldn't be globally voted by coins.
There is no other way.
Another way: Voting power by some logarithm of fraction owned of all coins, weighted by account age. The latter discourages endless scattering of NXT to circumvent the logarithm (which would be a real problem in a naked log system).
As if there is not enough bugs to fix already... now NXT needs more bugs with complicated algos to calculate votes, min fees, etc. I'd say, until major bugs are fixed, like those that allow to take down the network, everything else should be as simple as possible, no complex algos.
