Yes, for quite some time already. I'm in the EU server, lvl 27 Slayer atm, IGN Sanktum. I'm liking it so far, though my fps is fcked up (with almost all games and i need to send my laptop to the warranty repair thingy) and it makes things more difficult, but I like action MMOs and I chose C9 because Tera is p2p and the char customisation sucks in Vindictus and some good action MMOs aren't out yet. There are haters who say that it's a ripoff of Vindictus, but I don't care, I still enjoy it.
