KQo is a trouble hand and should be treated carefully. Behind limpers I'd limp because it still has value. Alternatively raising may buy you the button, which would be the only reason I'd raise.

I much prefer raising hands like 76 from late, because there is a lot of disguise to that hand, you know when you've made a big hand (or are drawing to one) and you'll have position. KQ can hit and be a massive dog.
