Yes, i agree that climbing is annoying, but its a challenge. Im not against the idea of letting players fly there, but it wouldnt be as much fun, i get super irritated when i climb to Sky's Rim (Because i never use the 'Set Home' thing, because i think its kind of like cheating :I ), but when you make it to the top, its quite satisfying. The first few times are hard i know that, but doing it more than once after a while makes it easier, and takes up less time.
