User blog comment:Gnomeco/Katarina - Should be buffed?/@comment-1330314-20140415125704

None of the buffs you propose would actually solve the problems you see with Katarina. In fact, she is a notorious pubstomper because of her extremely high damage, which you're proposing to buff across the board, so you'd just worsen her issues.

Fact is, if you're diving in as Katarina and getting CCed out of your ult, that's a mistake on your part: Kat's meant to go in after the tank/bruiser initiates and soaks up all the crowd control, and takes down priority targets when they're vulnerable. This means she's extremely dependent on team coordination, especially the tank. I think she does have problems, namely an extreme dependence on snowballing, but that's not an issue your buffs would resolve.
