According to champion.gg, Karma is the one of the worst "real supports" and champions like Kled, Swain, Akali, and Pantheon are better options for bot lane in general.

Is Karma garbage right now? Yes. However, you have to put Play Percentage into account.
0.3% play rate (56.81% win rate)
2.58% play rate (46.56% win rate)
8.54% play rate (51.84% win rate)
11.65% play rate (46.97% win rate)
Karma is played 8.5x more often than Kled support, and her win rate is 10% lower. Morgana is played 28.5x more than Kled, and her win rate is 4% lower. Pyke is played almost 39x more often than Kled, and his win rate is 10% lower.
Basically, Kled's viability as support is probably a LOT worse than 56%, Karma's is probably fairly accurate, and I'm unsure about Morgana and Pyke. I don't know the cut-off for having a high play rate making a win rate worse. The more people there are playing a champion, the more clueless people who've barely touched it there are. An example of this is ADC Ezreal.
Ezreal having a 50% win rate with a 30% play rate means he is REALLY strong right now. Ezreal ADC appears 100x more often than Kled support. His win rate might be lower, but the fact that he is played SO often means that his win rate would be disgusting if we excluded the people who are only playing him right now because he's strong.
I think I may have wasted 20 minutes on this. I probably should have just ignored the post and done almost anything else.
Hope I will meet some day trolls with "support" champions like these, so I can prove them, that Karma is one of the best supportive caster.
As a Karma supp, in a mid/late game I provide to my team a huuuge amount of mobility and shield power. Thanks to combination R>E I gave them first huge wave of mobility and shield power for all of them for a few seconds. This is pretty strong advantage for immediately few reasons.
1.) It create strong dominate effect in Team fight. 2.) Also usefull for engages. 3.) If needed, even for escapes.
This is however only the beginning.
For engages I more like use Shurelya's Reverie, which can be also used for escapes. This is second huge mobility effect, that I provide to my team with Karma.
Still, far from over with this support.
If it comes to a dangerous situation in Team fight, I always have ready to use combination of Iron Solari + Redemption. So it is pretty strong control over Team Fights and my team dies very rarely.
Now imagine that this everything is supported with Ardent Censer or Athene's unholy grail, which will make my shields from all sources even stronger and also provide another effects to whole team.
My Q and W provide strong cc and on top of that everything, later my E have about 4-5 seconds cd and like 10-12 seconds cd for R, so I can shield my teammates forever.
Pretty impressive, right?
I can make from my team an unstoppable force of destruction in mid/late game.
Don't even come to me with these troll picks. They're nothing compared to my Karma and never will be.
