I don't understand the way you make impossible to get the netting and make ghillie suit, I don't see the huge problem on giving people possibility to get the character ROLE-PLAY they want. And I really do not appreciate stripping me from possibility to find the components and make my own ghillie... And I want the ghillie because I think they look great, are fun and it is great way to be stealthily, so great defence tool.
My conclusions:
Very small availability of the nets will cause the players to kos others to get ghillie or to stay alive in ghillie, before I haven't even noticed anybody cares about my character ghillie because you could make your own relatively easy.
