Nerfing Karma While She's Hurting??

A bit puzzled by why Karma is getting nerfed. (Really?? Why are you doing this Rito?)

Look, I used to enjoy playing her but she is really hurting. This upcoming nerf really does just not make much sense. If you check at how she is performing in ALL tiers (from Bronze to Challenger on op.gg, League of Graphs and LolAnalytics), then you would note that she has really been dropping gradually in winrate since about November of last year. The only way that you can get her to work at the moment is if you really push your lane from the start (as we have seen in LCS/MSI play) - and this is just daft for what is supposed to be a support champ. And, now you have the idea of nerfing her is by chopping at her shielding ability? This literally does not make any sense.

Heck, this makes about as much sense as the reducing of Rakan's shielding ability and increasing his E. And as much sense as the reducing of Lulu's shield. They are support champions, Riot. It seems that you are chopping at the ability of supports to shield their ADCs and we'll be back at the "gangbang gank botlane" philosophy (to borrow Aphomoo's expression).

Please use a bit of common sense, dear Riot devs. Right now, you are putting the support role (and our accompanying ADC players) into a really weird place. I can read the tea leaves and tell that you are wanting us supports to go and start playing more champs like Braums and Alistars - but I can also see in those same leaves that the result may not be what you wish or desire. PLEASE be careful how you tinker with the play in non-LCS play. Pretty please?
