I'm plaiyng a dunmer thief and i've realized, Skyrim is an unrelentlessly difficult game for anyone who doesn't use heavy armor
seriously, I go in to any dungeon and get my [censored] kicked...
What?!
I've been playing a thief build for 30 hours and I've consistently kicked ass.
Just a few salient points:
1. Sneak attack multipliers
2. Archery (x3 damage from sneak)
3. Daggers (x15 damage anyone?)
4. Poisons (Seriously. A little Stamina sapping, paralyzing, or health destroying poison goes a long way.)
5. Enemies are attracted to sound. An arrow against the wall on the other side of a trap will attract your enemies and cause them to stumble into their own defenses.
6. Playing a thief requires patience and planning.
As a thief, you shouldn't need heavy armor because you shouldn't be getting hit. If they've seen you then you failed. I've taken out entire bandit dungeons without being seen. You can't play a pure thief build like a warrior.
