I had 2 of my 6 accounts hacked but only cos they broke into my NCSoft account and changed the passwords from the website. I'm still trying to figure out how they knew a character from the 2nd account they managed to access.
The main problem with GW1, was that it was originally designed as a PvP game, with the designer thinking that most people would progress to PvP once they'd finished the campaign.
What ended up happening is that they underestimated the amount of PvE that the players wanted to do. And because all the skills were the same in PvP and PvE, what ended up getting nerfed in PvP because of abuse, ended up affecting PvE as well.
And as most monsters in PvE, used the same skills as the players, PvE became 'not as difficult'.. Leading to more abuse in PvP, more nerf's.. rinse, repeat.. until some people said they could face-foll PvE..
Generally PvP'rs and PvE'rs don't mix, without a lot of name calling and Elitism.
