User blog comment:Usiar/Jayce -- Too much free damage?/@comment-75.22.116.226-20130212012245

I know this is late but free damage implies that a champion doesn't have to build that much damage to do damage. Jayce has good scaling, but he won't do much damage unless you build it on him.

Champions with tons of free damage would include Olaf, Irelia, Darius, Xin Zhao, Garen, Wukong, etc. Jayce tends to build much squishier than they do if he wants to get the most out of his kit.

Back when Thundering Blow had base damage this would have been true though.
