I'm not staff or anything but I figure I'll give my thoughts

An indestructible weapon really is not that big of a thing. How often do you actually see a tactic that revolves around the other guys weapon breaking? It happens, but not very often. It takes way less energy to get something out of the way than to break it.

Even as a shield its not that bad. Captain America has an indestructible shield and honestly he has one of the less helpful special tools out of the entire team.
