Well, not exactly...
Armor durability...the chance of it ever running out, even with leather, is very low. I do not believe I've ever had one of my leather helmets break, and only once have I had a gold one break, so I mostly ignore durability.
Saturation, on the other hand...I've learned to always have it as high as possible upon entering a battle. I mostly ignore my actual hungers state itself and simply eat food for saturation. You'll even see me running around just before corn refill simply so I can eat a steak for saturation since I'm expecting battles, even if it heals only half a hunger point. xD
