Wait... what? Mages received ALOOT of stuff in both dawnguard and dragonborn, way more then a theif character for example.
But i do agree that the desctruction magic school could use a rebalance.
I agree. They did get alot of stuff. But look at it this way. The witches have there black robes. The vampires have their armor. Us mages have to share our robes with the Stendarr, and all the robes look the same and it is hard to see the difference. Dragonborn did give some new robes, but the main one, Miraak's, is not good for inside a town where someone can attack you. All it takes is one hit and there are tentacles hitting guards, npc's, etc. They are good for outside of town, which is why I love them.
But as a sorceress / mage, I want something different. I want a mage set of robes, both enchanted and un-enchanted, that are seperate from the Stendarr, and have a look all there own. The cultists robes are great, have only 1 enchantment, but they are hooded.
