Frankly ever since I started the game I always went with whatever I felt like doing. I don't care about how good the suggested builds are, and I don't care either if mine makes sense to others or not. What I most love about this game is the fact it's customizable, and if I took that away from it and started playing someone else's premade build, I'd have no fun at all.
I play an assassin imperial woman, that uses a two handed to murder, is a vampire and loves lightning destruction spells. Does it fit any of the archetypes? Nope. Do I give a damn about it? Nope.
My Night Reaver is a good example of my attempts to break the mold with what looks like, on paper, the worst possible racial choice for the build. Nords gain no bonus towards any of the skills used in that build. Despite that it all works out so well seeing as Nord vampires are essentially immune to frost damage, and Battle Cry + Marked for Death make such a brilliant combination.
Lore wise its always great to see a build that breaks away from the supposed norm - the stereotypes. I think its reasonable to assume that not all Khajiits are skilled cutthroats, not all Nords are brave fighters, and not all members of a race worship the same deities. Odd-ball concepts like an Orc mage, a Redguard necromancer, or a High Elf knight tend to attract my attention more than builds that stick to the norm.
Good discussion Arcanus. I have always enjoyed playing a Cleric class in table top rpgs and exploring how clerics of the different faiths would be. I think my biggest roleplay challenge in Skyrim was a Khajiit Cleric of Alkosh which was inspired by a mtg card. Balancing the cultural and racial attitudes of a Khajiit with that of a traditional cleric was interesting to say the least.
It turned into a stealthy, thieving (borrowing) righteous warrior which could only work as a Khajiit.
