What would you like more, multiple smaller stories where you are a normal adventurer or do you like one big story where you are a champion, like the last couple of expansions.
Personally i'm getting tired of being the Champion, what you?
Edit:
My view:
Adventurer: Wandering hero helping out where able, if needed helping to destroy <bad>.
Champion: Revered Commander/General/Champion semi-leading the campaign against <big bad>.
