Well yeah I know lol - but putting them back into the overworld in seemingly climate-appropriate locations is far better, and helps create more of an "adventure" feeling IMO, rather than just "oh here they are in the endless raid dens" or the other approaches, it feels more authentic to me.
Also, noticed this in the trailer; (spoiler cause big?)
Are we meant to know who this is? the cut off and the surprise is on purpose, so it's a reveal - I want to say it's Penny but like dressed down? But the red shade isn't the same, and I doubt they'd sap her character for some sort of "I've bettered myself!!" reveal?
it could also be nothing but the framing is too suspicious imo
