I physically only have one arm, well one and a half, but I was able to do the entire thing in an afternoon ground mounted.
it is not such an insurmountable task that it cannot be done in a reasonable amount of time. It also helps that there is no place that requires flying that doesn’t also have an NPC or FP to facilitate movement.
I do however think that because of how minimal requirements for pathfinder are compared to past versions, that both flight styles are likely to be unlocked going forward without pathfinder, however if pathfinder continues to be as minimal in the future as it is now, I don’t think I will have an issue.
