Well, when it comes to duels it is very hard to tell the difficulty of the fight. The reason being that people upgrade gear differently - some opponents may have a very strong armor but a weak helm or a very powerful weapon but gimped armor etc. So unless you manage to hit them in the right place/avoid their attacks successfully you might face difficulties with the fight irrespective of the opponent's gear power.

As for equipment management and quest difficulty... No there is nothing wrong with how you're handling it. Unless you constantly upgrade gear, you will eventually hit a roadblock in the quests with fight difficulty rising to hard, insane and eventually impossible after every 2-3 fights.

That is fine however. With a little patience and skill it is very much possible to complete the missions even in impossible difficulty. If you are able to beat these fights in insane mode like you said then it's actually a pretty good thing :)
