Yea, NCsoft has some of THE single most antiquated and fucked up system for account management. I had issues with GW2 that took me days and many escalations to solve, and my problem is still there. Its like each game they make has its own system for account management, and then they jammed them all together under one name and assumed it would all work out fine.
Oh, and its very insecure as well, GW2 is the only game i've ever been hacked on, and when that happend I hadn't even been playing, and NO other game that I was playing at the time or when I was playing GW2 had any issues. And that was with their "IP Secure" bullshit thing, my IP from California, hackers from China, yea thats legit.
imo, if you want to spend the time getting your NCsoft shit cleaned up, make sure you use a password for that account that you use for NOTHING else, and write it down somewhere, then go through and log in to every game on your NCsoft account and make sure the password actually stuck, most times it doesn't, so you need to set it to the correct one multiple times.
TLDR: Ncsoft blows ass and I hope whoever is in charge of their account management system loses his penis in a tragic pencil sharpening accident.
