Who even asked for these Karma nerfs/buffs? Will we get something done about a champ that needs it?

So I have been a main for a while. I wake up, make myself breakfast, check my computer.. aaaaand I see stuff about Karma. Being the dedicated Karma main that I am, I looked at them, and these are my thoughts on them. Passive - Small changes.. don't seem to be noticeable. Q - unchanged, I like that. W - can now be cast on monsters -- This is going to be a nerf to mid and top Karma, because if you misclick, you will hit a minion (or is it just jungle monsters?). Anyways, this is a HUGE buff to jungle Karma, which was already pretty good, but now it's going to be just plain op. RW - Riot seems to really want Karma to just become a support.. seriously? They removed the healing and extra damage on her W.. They made it way more similar to old Karma's W. Very unhappy with this change. E - Lowered mana cost.. I'm cool with that. But they nerfed the shield amount? It's already a pretty small shield.. what was the point of this.. RE - Removed the damage component.. balance team really really likes Karma support, huh? Increases primary target's shield.. this is.. interesting..

The point of this post: Why was Karma buffed/nerfed? She was a totally fine, balanced, viable champion. I am not a fan at all of these changes. They sound good on paper, but once she starts getting played more, everyone is going to whine about how broken she is. Then, Riot will pull some huge nerfs on her or something, and she will go back to shit-tier pre-rework Karma. Riot, why did you do this? Nobody was asking for it. Why don't you nerf, say, oh, broken-ass Nidalee? Or any other OP champs that actually need work on them? I am happy about jungle Karma becoming a thing now, but overall, VERY unhappy about these unnecessary changes.
