So even though we are almost 6 years removed from the release of TechManual, I think this is a conversation worth having. as we all know TM changed the rounding rules to a "When in doubt Round Down" rule that affected Ferro Fibrous armor. this left a lot of canon designs with one point of armor mysteriously vanished.
the most common solution to this was to remove a point of armor from the rear center torso. now this is perfectly legitimate, simple and I have no real problems with it. what I wonder though is, could a few alternatives have been done instead?
the first that comes to mind for me is the Head. most of us, myself incuded, automatically pump 9 points of armor into the head before we do anything else (unless the design is 25 tons or less, but that is a whole different discussion.) it took the release of the Pariah, with its genius armor arraingment to show that 8 points to the head is not a bad thing. You still need to commit at traditional headcapper for one shot kills. under such a plan. and in terms of fluff you would have a perfect story of "not as well armored as manufacters have predicted" developing a great inside joke.
anyway that is my initial thought for now, there are other arguments like the front center torso, or making sides uneven. what do y'all think?
