I loved LineageII when I first started, played for nearly a year. The one consistant problem I found was that in a PvP based game one rule held true for all NA players - Piss off the Koreans by being better at the game and you become target #1 for all the Korean Guilds/Clans. I was a Priest in LineageII which is healing/support and I had to quit because three different Korean Guilds had what amounted to a contract on me. No matter when I signed in they had members looking for me and the GMs always said "it's part of the game". At first it's sort of cool being so feared or getting that much attention but after being trapped in a non-PvP town for 2 straight days it stops being fun. Don't take my word for it because you really need to experience it first-hand to understand...just be warned.
Thank you.
