Bretons were always talked about as masters of magic, but in reality, their passives aren't really up to par with the Altmer.
ALL of the Altmer's passives are pretty damn nice. We're looking at:
- 4% increased damage with elemental abilities (fire, shock, frost).
- Increase max magicka by 10%
- Increase magicka regen by 9%
Really nice. Looking at that list, there's nothing that would make me hesitate - I want it all.
Now, let's take a look at the Breton
- Magicka "Mastery" gives you 3% reduced cost on spells (lol, using the term mastery is an insult)
- 3960 spell resistance (absolutely useless)
- Increase max magicka by 10% (Really nice, but Altmer has this as well)
The only good passive is Gift of Magnus (10% magicka), but our friends the Altmer have it, along with other nice passives. Let's be honest, 9% regen is going to help you a hell of a lot more than a pitiful 3% cost reduction, which you will barely notice.
Breton needs a buff. Either increase the spell resistance and cost reduction, or replace them with something else, like
- Hand of Julianos: Increase spell damage by 162
- Atronach skin: 8% chance to absorb a spell, adding 80% of its cost to your magicka reserves (or just a fixed amount)
These are just examples, basically something that makes a difference. At the moment, Altmer just seems like the go-to place for magicka classes, unless you want to look Human and could care less about passives.
