I think Skip should (and could) be used to make a badge harder to achieve and teach reviewer a good habit along the way, like:

awarded for 1000 reviews and no less than 25% skip actions

^{Per my experience, a healthier dose would be like 50% skips, but for teaching purposes, 25% could probably be just fine.}

Note how electorate-badge has an additional requirement somewhat similar to above:

you must have voted on at least 600 questions and of all your votes ever cast, 25% or more must have been on questions.

Have to admit, my own voting habits were rather heavily tilted on answers at first. This changed right during my first hunt for Electorate badge, which taught me to vote on questions.

Hopefully additional requirement will teach (at least some of) reviewers to be less reluctant to Skip.

Above means, fewer than 25% skips would block receiving a badge.
