Karma's Ability Changes are HORRIBLE - KILL Viability
Q is a buff because she gets more frequent Mantras from it scaling. That's fine, she's already underplayed, this will make her very strong enough to get popular.
W being minion targetable is great. Jungle Karma is a thing, and healing off of minions makes it so much better,
Mantra'd W ---- RUINS Solo Lane Karma and CRIPPLES support Karma. She goes from 40% of missing health healed, to 20% of damage dealt..in 2 seconds. Then it removes 75/150/225/300 (+ .6 AP) bonus dmg in place of 10% total damage............
Karma before scaled her heal with both health and AP. Ignoring AP, Assuming Karma has 800 health but was brought down to half, 400. She would heal 160 health. The New Mantra'd W, would heal 20% of 60/110/160/210/260 + 1 Q 80/125/170/215/260. If both Q and W were rank 5, she would heal 104 health. At level 13, which is what she would be maxing 2 abilities, she is healing 104 damage no matter how close to death she is.
The 10% of damage dealt in 2 seconds makes no sense. That number is so miniscule compared to the amount that she loses, that you would need to coordinate to use it with a mage for it to have any relevance. 10 health every 100 damage versus 75 to 300 dmg scaling. Have fun having your team spend 3000 damage on a single enemy to make up the difference.
These changes should have been reviewed by many more people to help point out how ludicrous this is going to make her.
She's becoming a blur in the list of supports because she's losing her uniqueness. In place of damage, burst healing, she's getting her ability to kind of heal other allies something lower than herself and more frequest mantras to continue only using it for Q.
