Grindfest Alert, Grindfest Alert! Cabal is strictly for hardcore players only.
Cabal probably wouldn't have been a bad game if it steered clear of the grindfest trap a lot of developers fall into but unfortuntely this game is all about the grind and it quickly gets boring fast, probably the reason why there are so many PKers running around because there bored out of there minds.
Later levels you could easily spend countless hours skill grinding or level grinding most non-hardcore players will most likely quit the game halfway. Personally, I wouldn't give this game even a remote chance unless your a hardcore player who doesn't mind the atrocious grind Cabal offers, to be honest its not even that great of a game to be worth putting in precious hours of gaming - look elsewhere and you'll find better free to play MMos.
