Breton + Heavy Armor + Alteration + Spellbreaker = OP?

[Cathulhu]

When i created a new char based on Heavy Armor, Maces and Shield combat i thought up this:
1. Breton, 25% innate element resistance
2. Heavy Armor to resist damage in general
3. The Shield Spellbreaker, has a built in Wardspell
4. Alteration magic, not only increases it my armor, it also grants 30% additional element resistance.
5. Maces, i love damage ignoring armor and the Mace of Molag Bal is the best Mace i have found so far. Very hungry for Soul gems though.

Even with Deadly Dragons mod set to Expert difficulty, i barely get damaged by Dragons. Shield up and the ward absorbs so much damage. Shield Bash the dragon and power attack it in its face.
The regular difficulty setting is Expert too.

Their breath attacks are pretty much ineffective.
For ranged attacks i use a crossbow. I prefer them over bows on this char. I additionally dabbled a bit into Conjuration but the summons seem a bit squishy.
