Completely agree. "Grind" has just become a four-letter word, that's all. I'm from DAoC where quests were kind of an oddity, apart from your class-specific epic series. You even learn to play your class better in a "killing mobs to level" situation, because on the whole you're spending more time in combat! That was certainly my experience, and you can learn a lot more than you think by just putting forth the effort to pick up on things you wouldn't have noticed otherwise and not turning off your brain to go on autopilot to grind.
