im not saying casting options for each one, im just saying the category for classes should be separate
Why? The whole point of having the "Magic User" superclass is so that you can point to them and say "this uses a casting method i.e. magic." Druids, Clerics, even Warlocks IMO, all use magic...hence are Magic Users. Even in 4e the words "Divine" "Arcane" and "Primal" barely have meaning, and have none mechanically. Just (as a default) keep them as tags on the classes for traditional campaigns.
