I think if you bypass x-trap, you cannot play Elsword. Like if you cancel the GameGuard at GCPH, You cannot play it. But when you play with it, Its ok. But Im not a Hacker, So Lets wait for anyone to share their expierience. =)
Actually there is a WAY to bypass Xtrap like they did to CABAL.... but i don't know yet if the Elsword itself will scan the Xtrap if it's successfully deployed or not (vise versa...)
