Barbarian unnarmored defense is still dogshit

The feature just makes the Barbarian absurdly MAD and it isn't even better than just plain medium armor(even worse when adding magic armor). Really they should have made it scale with STR + Con instead of dex. Monks don't have this issue because it uses both attributes the class alrrady needs to be good. Barbarians on the other hand need dex and it makes it so much harder to increase it.
