Ahem,
If it was Pay2Win, it would mean that any fool could use real money to buy a superpowered weapon and armor (Let's call them the UBERPWNZ SET for this purpose). You see, a player has zero skill (a noob if you will) so he cannot get gear that allows him to fight endgame bosses, yes? So he buys the UBERPWNZ SET and suddenly he is a one-man raid, facing Styrak and taking him down before he even gets to use Chained Manifestation. But if he uses CC to buy stuff to sell it it for creds, and then uses those creds to buy Armor Modifications 30, he still needs combat skills (also if he sets his gear up badly, it doesn't matter what level the mods he used are), and a skilled guild to face the endgame bosses, so he can earn the true mark of power, and that is the achievement you get for beating them. So if he is useless as a player, he is now stuck with gear that is not top spec, and soon will be outdated when new tier is introduced (it means that 32s are coming with NM modes and 31s will be lower tier now so it does not matter if they become craftable), and he'll never be able to get the best gear and vanity stuff from bosses. And only things that happen is that BW get teh cash for CC and crafters get a motherload of creds, so if anybody is stupid enough to do this he will only help others, but not himself. Unless it's a (rich) pro player who is lazy to gear yet another alt and uses this method instead, only he would probably craft the stuff using his alts or get the mats for his friend/guildmates to craft them for him.
TL;DR - to sum it up:
Buy UBERPWNZ SET that allows you to face tough bosses alone and kill them easily, or at least makes you very powerful = Pay2Win
Buy mediocre raid armor that you need to properly assemble yourself = NOT Pay2Win, Pay2BaseGearYouAltBecauseYouAreLazy at best (worst).
