Exactly! Recent weeks we have witnessed bunches of masternode coins released; and as you stated they almost have no idea or detailed plans about what they should and have to do to develop their projects. Those projects are likely scam ones.
DeviantCoin is one of the best POS/MN coins in my opinion. I did loads of research before investing here, and the majority of the other coins on MasterNodes.online are just purely a currency, and on their road maps have things like "Planning on being the main crypto currency for commerce" along with other vague claims whilst offering no solutions how they're going to achieve it, and no features other than POS and MN.
It's good to see Deviant developers has released the project roadmap with very specific objectives and detailed plans to reach their ultimate targets.
I love that Dev is working on a decentralised exchange along with a hard wallet, and also has great returns for investors.
