User blog comment:Sgt. S.S./Are dragons possibly too much of a challenge?/@comment-4113369-20120227105938

Eh, so long as you don't powerlevel your character by advancing smithing, enchanting, or archery (using Faendal) early on, the dragons shouldn't be too hard. For the majority of the game, Draugr Deathlords are gonna be your biggest worry. Elder & (especially) Ancient Dragons can be a pain, but they don't start appearing until you reach the thirties.
