The karma rework we really really NEED!

So i've played Karma a few times, and I always get the impression that she is a bit lacking, both in gameplay, fun factor and personality. Basicaly, she just appear to be kind of bland. So i thought a bit, and came up with this (totaly new) kit, that i feel would give her a lot more depth while remaining true to her character:

Passive: bonus abiity power based on % of missing health

Q: Cone attack dealing damage to opponent Bonus effect: allies in the cone are healed

W: a tether that can be cast on both allies and ennemies, applying a slow or speed buff. Ennemies that pass through the link are dealt damage. Bonus effect: amount of slow and speed are doubled

E: shields and allies Bonus effect: deals an aoe damage equal to the value of the shield

R: allows add a bonus effect on an ability. Relatively low cooldown. Able to have a maximum of 2 stacks of it at once.

I leave the fine tuning of numbers out, since balancing is a very touchy job, but I'm sure that with this kit Karma would be really really more fun to play and add more variety of playstyle to the support pool.

What do you guys think? I really really think it would help her make her way back as being a staple support and not just a niche pick­
