@midnightwish:

Looks to be that a bunch of wallets are staking without properly rewarding the masternode % of the PoS blocks.
Please look into this right away and push for an update that forcibly drops the offending/outdated clients from the network.
Otherwise, this remains a fundamental flaw in the masternode incentive. You can take most of the higher positions on the richlist as examples of this behavior (though not all of them).

On the other hand, if the coin will be 90% mined by the time you manage to get a working GPU miner released, it will probably not matter much at all that you fix the issue with masternode rewards (or anything at all). Would be good if you'd settle some deal with djm34, or any other capable miner developer for that matter. IIRC, OCMiner had said much earlier on, that it would be a 5 minute job to get a cuda version made. He's either lacking the 5 minutes, or perhaps the task was underestimated?

It's nice that you've approached this coin with a new algorithm and all, but if you keep ignoring the current flaws in distribution, there isn't much to expect ahead. One positive impulse right at hand, is awarding bounties for community contributions. I hope you can overcome these few hurdles and drive the project forward.
Best of Luck!
