Make karma account wide?
Karma, like skill points, are part of the character’s progress.
As much as may of us would love to have that, this would defeat its purpose.
If you ask me, I’d just have all gold and karma shared account-wide, removing bank gold altogether.
But since you can already share anything you can acquire with karma that they intent to have shared (e.g.: recipes, ingredients) they’ll probably never do something like that.
Unlike dungeon tokens, for a character to get something with karma, that character must deserve it.
