The real problem with Karma is that she's a support build towards melee adc's. Even if you play hey mid, and you win the lane (which is not rare, karma has an amazing laning phase) in teamfight you'll find yourself using your skills on the initiatior more often than not, leaving your ranged adc without support, and if you use them on the ranged, you're only getting half of the skill and missing on damage.

I've laned karma+ww/irelia/jax/lee bot (with friends, of course), specially when there's an opposing darius top or something like that and we can put our ranged adc on top, and it was glorious. Melees with jumps/dashes/blinks are what her skillset is made for, and you outlane almost every bot combination. People don't know how to deal with her, don't know how to deal with a laneswap, and vastly underestimate how tough the lane is.
