When it comes to ‘balance’ in a game, everyone is an arm-chair developer. Reading forums, you’d think that creating class balance was the easiest thing in the world, and it would be so obvious when class balance is off. That rogue who can stock lock you for 4.5 seconds once every 10 minutes is clearly overpowered! Healers shouldn’t be able to heal themselves in PvP because it’s unbalanced and they can’t be killed. There are a thousand examples that anyone with keyboard and a tenuous grasp on the English language will give you, often whether you want them or not.
