ArchlordPie's idea pretty much solves any potential abuse issues i can think of. You already have an instance, its already live(so not possible to try and fish for good spawns). Just keep it going while you're disco'd. Mobs keep spawning, patrols keep moving, and most importantly timer keeps ticking. The only specific thing i would add to what he wrote is that your character doesnt just vanish when you disco. The game treats it like you trying to log out in an unsafe area. It takes 30 seconds for you to vanish. So you discod during a boss? It probly killed you since you stopped fighting back, but it if was weak enough youll get a fair shot at it.Once you vanish its gonna reset to full health and move back to its default position. Then when you log back in, depending on where you were standing compared to its default state, it might start whacking you before you even have control of your character. And again, the timer is still ticking. If your hour runs out(online or off), you still fail. This would save some runs, and i dont see where the exploitations would be.
