For the masternode owner it is good; for the miner, not so good.  We have been discussing making adjustments that minimize the impact of any changes in percentage to the masternode owner, while also providing more incentive for the miners.  As we have seen multiple times in the past month... miners are essential to the stability of the network.

To your question, don't always look at the percent of the reward, but also the amount of the reward compared to the block time and the max supply of the coin.  For example, some coins out there look amazing at the surface, but when you think about it a little, it's really "too good to be true".  For example, a coin that gives 90% to the MN and 10% to the miner may have network issues if the miners all leave.  Combine that with a high payout, like 20% of the master node collateral for a block reward looks promising, but if you do the math it could turn out that is only sustainable for a couple months before the max coin cap is reached.

There is a balance that is necessary to keep both the miners and the masternode owners happy for a long life of the coin.  This often is not nearly as attractive as some of the coins that are out there; but that balance is necessary for a long stable life of the coin.
