In the D&D world there are such things as "stupid" mages, they are called "sorcerers".
HEY. What did we ever do to you?! It's not our fault you have to "study" magic when it comes naturally to us
If anything, wizards were so stupid, they had to become more like sorcs by changing their memorizing mechanic to skip number of uses per spell
. Just envy mate every mage wishes they could fart chain lightning and breathe fire.
