I actually disagree with it being well designed. The weapons are too common and break so frequently I feel like I'm playing a weapon changing simulator. They have never been a limitation and I have never worried about finding a new weapon to use. However I do find myself constantly having to bring up the menu to change weapons. I have 12 weapon slots and pretty much every slot is a knight's claymore or guardian weapon.
Once you get to the point of farming the world minibosses you'll never find yourself wanting of a good weapon. Hinox and Lynel have good weapon drops and they drop pretty frequently.
I feel as though weapons should have been made more rare but more durable so that there were times when you wouldn't have a weapon because they were rare to come across and you'd second guess yourself about using your weapons on lesser mobs like red moblins or keese.
I find myself needing shields more often than weapons - since I like to go Guardian hunting and I kill them exclusively with shield parries. One or two missed parries and my shield is destroyed. While I rarely miss the parry anymore, it does still happen.
