@riot ricklessabandon - Karma is a primary mage, please consider this.
Just a friendly reminder for you that Karma is a primary mage and secondary support, like Orianna or Lux. And that this was the plan when she was reworked. Ask scarizard. I write this because your PBE changes make me worried you might have discarded this point.
"the goal is to make her feel better as a support, so hopefully stronger!" Every change that would make solo lane Karma feel worse would be a change against her design I think.
