About the Karma changes..
I'm not sure if I'm too fond about the Karma changes on the PBE, all three iterations seem like they're just trying to make her a support and ruin her solo laning, even though it was said that she was supposed to be getting late game buffs. Right now I think Karma is fine balance wise and don't really see the need for these changes, but a few things that I'd like to see stay are :
The W usage on monsters, doesn't really affect her laning much so it would be a pretty nice buff for the jungle Karma's out there.
But that's it, really, I don't see the need to change her any further.
