i actually finish the arr storyline twice in the old days using 2 different character because at that time i didnt realize you could just swap class freely lol

but i think there shouldnt be a problem with the transition, yoshi said they only "remove" the unnecessary one, something like the one that you need to do quest to prepare a feast before facing titan? i dont see any point of doing that lol they could just use cutscene about it and be done with it, but nope here a quest to collect food and stuff.
