Yes, the power usage isn't as good if you dual mine... But if you were mining DCR and holding it back then... It's worth $34 or so now, instead of $9. 

DCR is a great coin with a lot of potential.  I still have "some" rigs dual mining DCR.

Most people dual mine and do whatever is profitable at that moment. They don't analyze the potential for the coin long term.

we should mine for the highest current profit but at the same time trade for the highest potential.
