LeBlanc shits on Karthus early game, yes....... if there were no minions. But that's not how it happens. She'll get pushed to the tower very easily and if she doesn't play carefully and leaves the lane a couple of times to heal or dies, you'll probably lose the tower very quickly. And late game she severely falls off while that's where Karthus really shines. He'll also have a lot more farm. So, if you find yourself as LeBlanc versus a Karthus early game, you damn well better try to screw him over early game with jungle ganks (Karthus loves pushing) and proceed to gank other lanes and wreck the entire enemy teams (or atleast their carries, through repeated ganks) early, because late game LeBlanc becomes a liability. Scarra beating him was most probably a matter of skill, which is the most important factor in this game after all, but Karthus is by no means helpless against LeBlanc.

But, focusing on the topic at hand here, stacking full MR runes as an AP mid is actually very effective. This was one of the "secrets" of the higher elo players and what everyone was doing up there for a while, it made you ridiculously difficult to push out of lane by the enemy AP mid. That's why they nerfed MR runes in the last patch and buffed flat AP. Riot even specifically stated that the reason was so in last the patch preview video.
