You nailed it with regard to how few coins are actively staking, and I agree there needs to be some brainstorming done on changing the system. POS is a reward for helping to secure the network, and currently hardly any investors are doing that. On the flipside, that makes staking far harder for miners...
Thank you for providing your experience with V8 as well, it's interesting to see the very wide range of experiences people have had in the first week or so. We will probably have a better picture of the impact at the end of the month when everything has averaged out somewhat.
