I always start with Nord (not just because its Skyrim as I always have in previous) so I'm expecting to be quite lucky in choice of armor types.
After my first character I usually start using different races and I design characters built around that race and try to choose racial based equipment.
my second character is probably going to be a Khajiit so I hoping for a good Khajiit style armor that I can upgrade and make great. I'll have to wait and see.
As for Orcs I always use Orcish armor and Bosmer I tend to use Elven armor. Imperial I tend to go Imperial, Glass or Ebony (I imagine companies who are primarily Imperial run control the mines and export / import the ore)
I was curious what race other were playing with and do they have an armor they intend to use.
