I was recently confused on what character playstyle to use to I thought about which ones i did not do, and I came up with a pure thief. I do not engage in combat unless I have to. I sneak by harder enemies and groups. I only backsab when an opportunity presents itself. A hard encounter that I had recently was in Bleak Falls Barrow, a restless draugr was gaurding the door I need to get past, it was a small room with some pillars and it was brightly lit. The solution? Use arrows as distractions to get past. I thought that this would be a boring playstyle at first and it might be to those who do not like sneaking but i found it fun when I actually started doing it. You get the feeling of just being an unseen bad_ass.... it's great. I recommend that those of you who have not used this playstyle try it.
LOL when I was first doing my thief, there was this one place where a mini-boss dragur was guarding an Iron Door.
He would walk up to the door then walk away briefly.
As he walked away, I had like a second to get past him, open the door, then shut it.
Incredible fun.
