I cant get into playing as a paladin because the only good looking mace is the mace of molag bal... Is anyone else having this issue?
I think Bethesda needs to introduce some "Good Guy" weapons and armors.

Anyway I was thinking they could make a mace that kind of looks like dawnbreaker except pure white, and it could have a special enchantment that does extra damage to daedra.
Another problem is that there are no good looking shields or armor that a paladin would wear.

I think that the steel plate armor looks good for a Paladin, and so does Dwarven if you wear them with a hood. You can always enchant your own mace.

Also, what about the Aetherial or Auriels Shield?

I certainly agree that there need to be more end game options for armor that would suit a holy knight rather than a dark blackguard. Cosmetically you can wear steel or dwemer armor but you'll always end up wanting both looks and stats. Of course it shouldn't be all mirrored like in Fable where you just have dark and light counterparts of any armor, but there should be options at all levels of armor.

If i ever get dawnguard I'll tell you
