So, I have a question for Sam (and Sam rather specifically):
My GK techmarine, metal model, comes with what looks to me like an axe. I have options, whihc I pay pts for, to switch it out for various NFW, which would be legal, and require conversions. But changing that axe to a regular sword would be "modelling for advantage" by the same logic, right?
Furthermore, other chapters use the same model. SInce they don't have options to switch out the main weapon, does that mean all regular techmarines have power axes now? +1 Str, i1?
