Let me just say this, because I use Karma all the time and I usually never post. Karma is an amazing mid game and late game support.
All I do is build ap and it usually works out. You let your carry farm and only take if they arent there, you'll make money off of assists and kills sometimes if your lucky. Mid game, when people are out of lane, make sure you're in team fights and get assisits and kills. between that time, farm. Because you need it.
I always end up building ROA, CDR boots, WOA, and Rylais in the end and Morello's, jsut be patient and don't die. I usually do well, just keep going for an ap build and it will get done no matter what. and being a support, you get assists usually, no matter what.
It's not the CS that'sthe problem for me, it's usually my laning partner that doesnt understand that I can output damage while keeping them alive. It frustrates me when they run while I have a shield and heal up. Anyways Karma is strong champ and she's better in different compositions. Better in premades. I'll rape with her. Still viable in solo que. But I wonder what the remake is going to do....
also, I'll end up in every game with at least 150 CS and I never compete for it,and will gladly hand it over to any other champ if they're around btw.
