User blog comment:AwesomeBathtub/An idea for a Karma rework/@comment-6061249-20130129172834/@comment-70.61.75.234-20130129182938

I personally think the only rework Karma needs is a method for her Ult to be available on call. For instance, she gets the 2 casts as normal now, and those stacking casts are free. But while stacks are gone, each cast of her ult costs 50 mana, stacking indefinitely for each subsequent cast, and resets when a free stack cast comes back off CD.
