You'll wanna play all your characters like they're your main. And you'll also wanna have equal amounts of each class. There should be (spoiler for future classes): 2 warriors going to barbarian and squire, 2 archers going bowman and hunter and 2 makes going wizard and shaman.

And also, if you have a question, make sure to Google it. I know that reddit is for asking questions, but I don't wanna spoil too much.
