1) There is no in-game advantage, you're making that up, so right there your entire point is moot. Like I said they will be next to nothing and not desirable. What IS weak is trying to claim there is any advantage where you have no proof AND the history of the franchise sais otherwise. So yes it is just cosmetic. Nice try I guess, but without proof of what the racials are you are at the "very unlikely" end of the spectrum with this argument with them being anything special.
2) You say "COMPLETE race" like there is anything there to be "incomplete" it's a skin on a character model. You don't choose the races in game, so no it isn't even an in game choice. Other than aesthetics and racials, it doesn't carry over to in game. That is most likely why he used those exact words to save from any consequences from a cash shop because those words actually still stand completely true, there is no content (zones, quests, story, dungeons, bosses/raids, PvP) that you don't get with a sub.
So just stop and think, none of my other posts were irrational your "refutes" were actually just repeating the same misinformation you started with so if you still can't see how your making something out of nothing you are being irrational, or just purposely ranting to troll.
