any retailers selling this game??? and payment method?

hi i'm able to play this, how do i check my ping??? thanks. no lag for now but i really wish to noe my ping for overall so that i can decide to buy this or no.

hmm, when i use analog controller the camera/right stick is abit too sensitive, hard to aim. how do i set it??

ps : the battle system abit weird, especially when im using skills (the short cut key - 1,2,3...). sometimes can cast out sometimes is just like cancel it?? 

If you're Win7 user, you can check your Latency(ms) at Resource Monitor. Windows>Run>Resource Monitor, select/tick Tera.exe under Network tab, the Latency(ms) will be shown at TCP Connections.
