KQ is only really bad if your opponent has an Ace (plus the obvious monsters).

A hand like A7 is even worse if you know your opponent has an Ace plus it sucks against middle pairs. It just happens to be in pretty good shape against KQ.

The biggest problem KQ has is that when people raise its much more likely they do have an A, plus when you raise you don't have an A in hand to prevent your opponents from having it like you would with A2, so you get called more.
