In 5E, dwarves make interesting wizards thanks to their racial armor proficiency. You can go around in medium armor throwing fireballs.BioWare was right to bar Dwarves from being mages.
The problem is they do not get an onborn bump to intelligence. This means in point buy and stat allocation systems you start the game with a +2 in a main stat, not a +3. A trendemous disadvantage, I don't think its worth the extra AC. Maybe with Hill Dwarf for the extra hp.
