I apologize if this is something that has already been answered. I tried searching the forums using things such as "Layering Form Fit," "combine form fitting," and just "Form Fitting Armor" itself, with no applicable results. It's possible I may have missed something though.
I recently ran a game, and had an individual bring in a Minotaur with a Body attribute of 10, and a ludicrous amount of Form Fitting Full Bodysuits, each having the Gelpacks upgrade. He had something like, 50 or so ballistic defense dice, and around 36 or so impact defense dice to roll (including cyberware, bioware, and other variables for damage resistance). These pools were fairly high for a 400 BP character, so I asked him how he pulled it off or was justifying it, and he said that, as written, Form Fitting Armor is only counted for half when combined with other armor, and therefore, would only count as half when stacked with itself, so he could stack on A LOT of form fit, without hitting the 2xBody encumbrance cap. I asked him to tone it down to just one Form Fit suit, and some regular armor (and some Securetech PPP), and he begrudgingly did so. However, he did point out that in Lone Wolf Lab's Hero Lab character creation module for SR4A, this is entirely legal.
So I'm asking if this is even remotely legit or not, or possibly a bug I should report to them. To me it seemed a bit ridiculous.
