Dear devs. If you do not let existing characters to play prologue events, maybe do not have NPCs tell us that our character did something that happened only in prologue?
When I was retrieving Dragonhorn from the last Dragonguard hideout, Zamarak compares it to one my character used in Star Haven Adeptorium.
It got me really confused, as I had no idea what he's referring to. I surely would remember seeing another Dragonhorn! So I was wondering if I missed some side-quest I was supposed to do and I wasted my time running around Star Haven wayshrine looking for it.
And only after I made my necro, I realised Zamarak was talking about something players character does in prologue.
Which felt doubly frustrating, as prologue itself (just as the one for Summerset!) would be the perfect entry point to expansion for existing characters as well - setting up the stage for Chapter's main quest and making it more immersive than just travelling to wayshrine.
So if you do not want to let us play that quest on main character, at least have a bit of decency not to taunt us with implications that our characters was there anyways.
Some of us are here for story first and foremost.
