Nothing wrong with the game, I just got bored of doing quests and leveling and all the supposed fun stuff being at lvl 60.
Yea, the combat system is really nice, and so is the rest of the game play. However, it does get kind of repetitive since there aren't a lot of dungeons in level 60 that is actively run. (Besides some big 15v15 PvP battleground)
Kind stop playing at the moment when friends had to focus in school/life. Quest leveling also takes quite the time out of my day and returns barely anything. :X
Quest leveling is the slowest way to level. It is actually significantly faster if you just skip quests, and kill monsters with 2x exp.
