Well thats something you give up when you play multiple classes.

Best you can do is IsBoxer round robin using the cool down and range of the longest cool down spell and the range of the shortest spell. Far from optimium to be sure.

You choose spells first then once you have settled on the spells you prioritize you take the classes that have them.


You could make a longer round robin and the spell with the longest cool down fires one time vs. two times for the others. Not much you can do about range though except simply not use that spell and take it out of the rotation.

Multi classes have much advantage but this is for sure their disadvantage.
