So, under the paradigm where there are only five schools of magic, do you adjust the number of banned schools for specialist and focused specialist wizards? If so do you just switch everbody to the diviner standard?
This is getting me thinking; I honestly don't know if it should be or not! I didn't think of it but...
With the MTG feel that was mentioned about it, it would make perfect sense to keep it at two, since each color had two enemies and two allies, bla bla bla....OR, perhaps ban 3 schools entirely to only learn two, such as red/blue equivalent schools, etc., or something.
On the other hand, if the wizard still wants to be versatile, then maybe limit it to just one school?
