That is, a build based on the Dragonborn presented to us in the trailer/commercials and all the pre-release stuff.

I know people have done it.

What was the experience like?

Id like to know this as well. I guess the only thing that bugs me is you wouldn't benefit from the armor perks really because of the mixing.

You can benefit from all of the perks that don't require a matching/whole set, at least.

True true.

I've never tried it out before, I could never really get the PC to look exactly like Trailer!Dovahkiin.

I asked this question a while ago. I started the build actually a couple days ago. I wore the same armor, used the same weapons, and my main skills were Blocking and One-Handed. It's ok, I've had better playthroughs, but it's quite challenging playing on Legendary.
