My group has observed that "Mists of Ravenloft" is something of a narrative oddity. The main story arc completes at nominal level 12. But if you want to face down Strahd himself you need to wait until level 32. It feels like it needs a heroic version of the raid at about level 15.
Narratively, Strahd is powerful, but not demigod level powerful. It would not be unreasonable for high level heroics to put him in his place.
