Like someone else said, dying is the inconvenience. There are fights where you're guaranteed to die the first couple/ten/twenty times as you learn it. The fact that I have to start the entire thing over again, waste food, roll the RNG on boss moves, and hope everyone can perform exactly as before save for the last part is the inconvenience. I shouldn't have to run back to camp and dump gil into repairs or forget my weapon is at 11% and have it break going through an instance.

I understand SE thinks they need some additional consequence to death, and that gear repairs offer a nice little gil sink, but I'd rather pay a higher fee in the wards than deal with the mess of repairs.
