I was just curious as to what you guys think the best strategy for evolving/leveling up is.
I finally started leveling some of mine up to epic, but I only have a few. I've focused more on getting my lower level dragons up to higher levels.

What do you guys think the best strategy is? Should I work on getting as many of my level 7 dragons up to epic, or should I focus on getting all of them up to level 7, as that is a lot quicker?

(I've been wondering the same for Fantasy Forest Story, though I'm sure it works the same for both games)
