Hey guys, I did play this game during Beta phase, I'm thinking to start playing, but here's some question and you guys might help me out

1. I can't really remember which region I play on last time, but I do have an SE account. Is the account bond with the region I registered?

2. Is offgamers CD key and game time card legit?

3. I notice that the data center can be change anytime, so is that mean either you're using JP/EU/NA account, you can still play in the same server?
