Playing with both NA/EU
There is no other way, as the NA and EU megaservers are separate data centres. you either need two accounts, or to pay to transfer
Resident smug Englishman on the NA servers, just because.
kitten guess I’ll have to save some money T_T that really sucks
The only other option is to delete all your characters and transfer at no cost.
Do make sure, if you are interested in playing WvW with your friends that their server(s) are not Full, as you can not transfer to a Full server.
Good luck.
