Any thoughts on the Karma buff?

There aren’t that many Karma mains out there, but I was wondering if anyone had any speculations on the size of the buff or what it is. In my opinion, that W needs to be completely changed. I don’t feel like the ult-w self heal fits on a champ that’s primarily played support. I think reducing or removing the heal in place for easier to land and harder CC would make her more viable against other enchanters.
