YouTube artist and Guild Wars 2 fan MattVisual takes a stab at World of Warcraft in his Get a Mac parody "Guild Wars 2: Vs Other MMOs". The man has a point.
Guild Wars 2's Karma System does indeed allow players to score nice gear without grinding. During my time in the game's beta I often forgot the Karma was there, pleasantly surprised when I finally clicked on a Karma vendor to discover I had amassed a small fortune.
That having been said, some people prefer to spend months gathering their equipment. Hell, back when I played the original EverQuest I spent months attempting to gather the components for a single epic weapon. It was a massive combined effort by my guild friends and I, one that ultimately brought us closer together.
So there's that, or you can just be handed the stuff. Which is better?
