What dynamics do teachers out there consider when determining which students should be assigned which roles? Another teacher mentioned that it is good to have a strong leader-type as the mage and more "rambunctious" students as healers. I'm not really sure I understand well enough how these roles work together to know what considerations I would use when assigning them.
I know students can choose their own roles within their group as long as there is at least one of each (Mage/Warrior/Healer) on a team. Does this ever backfire?
