Keep in mind the ratio of strengths to weaknesses too. Any Factory Judge looking at Power Armor is going to want to see a weakness to the armor. Master Chief didn't have a weakness because he's a Videogame Mary Sue. Lol.
So if your Power Armor has joints or a neck seam, just add those to the sub as weaknesses. Otherwise Power Armor subs can read as: I am immune everywhere, to everything. Which is exactly the process the Factory was created to avoid.
To note. Star Wars is a very comfortable genre to be extremely powerful in. It's got Death Stars and Sith Wizards everywhere. So being extremely powerful is pretty common place here. Alas, Death Stars and Sith Wizards almost always have a terrible weakness that, (once exploited,) makes them seem pretty silly. So try to keep the SW universe in mind as you go about building stuff. Otherwise you'll find yourself being a Quantum Crystalline Gundam in no time. (like me) Oops.
