I never understood the complaint about the durability system. Its entire purpose is to get you to have a varied arsenal during your time through the game, as well as reinforcing the theme of survival. You slowly improve your stash of weapons, using stronger ones in tougher moments while burning through the weaker ones on cannon fodder. Slash slash crash, whip out a new one.
Now, if you want to hear actual complaints on the weapons system: One complaint I had was the "super weapons" from the champions should have functioned like the Master Sword. Once you earned them, they should have had cooldowns. That would have given some sense of progression without undermining the durability system too much.
Another is that the actual weapon variety that we had which was useful was a little on the stale side. I hope we see more types of weapons while otherwise continuing the system. Have each one be slightly more diverse than before. If Nintendo can make Kirby be massively diverse, we should be able to have at least twice the variants of simple arms in this new game. They're creative folks!
So, yeah... weapons breaking all the time is fine. I enjoyed that part of the game. The negatives I experienced were a need for a bit more variety in the available options, "super weapons" only applying to Master Sword, and maybe give us a few more storage slots because even when maxed it occasionally felt like I had too few; due to the elemental variants and stuff.
