PBE Karma buff may be a bit over doing it?
I want to keep this short, so it would be straight to the point.
Right now I feel Karma's shield is both strong and healthy. This buff isn't exactly what she needs, even though its quite nice. I believe the best buff decision without over tuning her kit would to change her cooldown on her W (tether). Change the cooldown from a flat 12 to a scaling 14/13/12/11/10. I was thinking of 16/14/12/10/8, but that would be over tuning her W as well. I think this small change of 14-10 seconds to her w from a flat 12 cd would help out her late game a lot. Her late game is what a lot of people have complained about and would help. With a lower cooldown on her W she will be able to use more Mantras in team fights. She is in a great spot right now which is why I hope she doesn't get nerfed in the future with this buff. She is completely balanced and with good amount of play making and counter plays.
