Great suggestions from all above, the easiest way to lvl is doin your limit of labs per day, and auto training. you could even get some ex from farming with extra stam if you hit your cap.
will get there in no time.

60m with Scipio though? Blondie may have made royals an heroics a joke, but not that badly yet lol
Maby double that an you'll have a better shot. As matty once said; its not just the heroes you place in a good form to make things work.
