We were able to have many things in GW1 account based, Kurzick/Luxon title comes to mind first as I did a lot of JQ/FA. I think this would encourage people to grind less and focus more on playing the game. Think about it, if karma was shared across all characters, then what is stopping you from making a new character and playing through the game with them, enjoying a different personal story, learning new things. The main gripe I see about karma is that “I want all my karma, I want to farm for karma morning, noon and night.”. If karma was shared, you would never have to; just load up a new, lower level character and have fun starting all over.
