Not even really an issue once you get the Master Sword. Sure it needs to recharge but by that point, I have a bunch of strong weapons. Stamina is also a none issue even early on. You just find more creative ways to climb up things and fill up on stamina food. Plus at this point, everyone knows the slope run forward trick. Most games how it's implemented would be horribly annoying. BOTW makes it work. Not like you ever run out as there is always something nearby and with the TOTK fuse mechanic it's even less of an issue.
Oh and btw in BOTW you can repair weapons. Just throw them at an octorock.
