Like I said, it makes sense when the game is live and people can choose if they want to pay/play/post. However right now noone can pay nor play, but there are still people who can post which I am sorry, but to me doesn't make sense. I think it is the wrong choise and if they were going to do it this way, at least SE could have given a heads up about it.
About the trolls, I honestly don't think they will go for XIV anyway... because if nothing else I doubt they even know about ARR at this point. Even if there were some trolls though, I would think there were exponentially more good and constructive posters that would join and ask questions.
Haha I am making it sound as if this is the biggest deal ever which it really isn't. It would just have been nice to be able to take part in live letter questions etc and since I asked support and got an answer I thought I'd share so people wondering about it, like me, could get the information as well.
