about them using reversing models from MoC(which is illegal), why dont just try to make a agreement, to none use of the models from MoC, with them? Becuase they sure as hell has some other skins which are not stolen.
Besides.. if im gonna be perfectly honest, I believe that the making of call of warhammer will never be done, only the skins will be done.
A larger group would increasing the chance of making something big, otherwise it will take ages and people will just let it go.
