Level 8 for me I don't think I have been doing as many side quests as you guys, I just killed my second dragon. Found a couple of annoying bugs so far sometimes NPC's can get stuck in combat so you can't interact with them has caused me a a few lengthy reloads.
That's what I have been specializing in still have to pull out the two handed sword once in awhile though.
Killed 2 giants and a mammoth. Just lured them to the tower where you fight the first dragon, and let that invincible bitch distract him.
