Let's take this fantasy realism thing a step farther... A battle party sets out with a caravan full of supplies, including food, replacement gear, repair equipment, and a cook, armorer and whoever else they may need in addition to the battle party. The journey would likely take weeks to reach their base camp, and from there the battle party would trek into the mountains alone, in search of Titan's cave. After several hours of spelunking, they finally come across the monstrosity, and battle begins. Now whatever you have with you is all you are gonna get. Your armorer is waiting back at base camp. So you better have been prepared with your gear in the best condition possible. Because the battle will be long.
BTW: I have never come close to having my gear break when I started at 100%.
