I dunno, I personally like that these things are so different from the rest of the game. They add even more variety, and have tons of utility of their own when used right, able to fulfill many different roles if set up right. It ends up almost feeling like a whole separate entity from the rest of the empire, powerful in it's own right... but you only get one. It's not something that you can just chop in half and send to more than one place at a time. I have to be careful about where I send it, when, and why, if I want to get the most out of it. That's my experience with it, anyway. I get a ton of use out of these things.
Feh, this seems like another of those things where I like it a lot, but everyone else seems not to. Like those Astro Trains, everyone seems to hate those things, I think they're entertaining and interesting. Except the gravity trains, those just make me impatient. Gravity effects always do. Bloody Gravitic Command Stations.
