Do we really have to explain basic math?
Either it's more complicated than you think or I'm dumber than my fiancee thinks, so yes, please.
(The above situations are not mutually exclusive.)
You've got a point - sorry I blithely assumed it was clear (I do this sh*t far too much
). If there's any place we should have/make room to explain the finer points of the FC gear system, this book should rightly be it, and we can carve out space to do so (though I'm still not sold on illustrating every armor option available - coverage and fittings in practice however is an excellent idea).
