Definitely looks more like an expansion than a sequel. I’m guessing Blizzard have milked the original as much as they can - there’s only so many characters they can turn gay when player counts are drying up and the game losing popularity, or the money isn’t being made via in-game purchases. It all got a bit predictable and tiresome. They’ll bait a lot people into spending £40-$50 just by having a ‘2’ in the name even if the content itself is not a revolutionary step forward.
