I mean, you need the diving suit to get to the Rainbow Alpaca's hangout. Some OG vet could have got the hat before the restrictions and picked a different profession. It's not really fair to new players since everyone from 2017 could have the hat.
I know what Mech is going to say - 4 character slots, you can play all the professions and see it all, and granted, the Rainbow Alpaca is a lore thing, but yeah.
It's all good here man - I get where you are coming from. Who wants to lose things that they have had in-game for years, especially their favorite outfit? I think even if I make Sierepica a Scholar, I think that the Sleuth Suit is on another profession and I'm going to lose access to it. We're all going to lose outfits that we wanted to wear unless we can convince Mech to not do this to us anymore.
