I played a mage in both Oblivion and DA:O, two RPGs that I played a lot, and in both games I got really frustrated on this regard.

There's SO many armours, so many swords and axes, so many combinations, you keep finding better and better equipment all the time, but when it comes to mage equipment, there's just not enough options.

In Oblivion, specially robes, I didn't even care for it, it was so rare to find and when you did the magicka bonus didn't justify the lack of protection.

So, any information regarding this?

Robes have buffs that are really good for casters.

Mage's can use shield spells for extra protection, they don't need armour. Plus, the robes have really nice enchantments for magical characters.
