You're absolutely right regularjoe. It is a powerful weapon so you'd think they'd make more than one.

On the other hand though having multiple ones takes away from its uniqueness and in a way makes them appear weaker. With two, they are both taken out pretty quickly, not making them very effective war machines if they're so easily destroyed. But by having one it shows how even a direct hit to its main reactor didn't completely obliterate it, and that it was once again operational in only a few years. It takes two attacks to actually destroy it completely. But I think the argument can go either way, like you said.

And yeah, this is definitely a low priority change. There are many other changes that are more important to be made. This was just one idea I had not seen a lot and I was curious about other people's opinions and actually if this little change would have small or big affect on the narrative.

The Boba Fett removal is a good example of a change that needs to be considered. My only concern with taking him out completely is that is apparent death might become relevant in future movies. Seeing how he's one of the most popular characters and how ROTJ is canon this event will likely be referenced if he is brought back.
