Some jayce players build full damage and they go for that classy e q poke **** when you can just build bruiser and do the exact same thing and not die in the process. This build makes you insanely sticky with really good burst and dps. As long as you are vs a team with mostly ad champions its freelo, if you are vs a ap champion just switch ghostblade for maw and ninja for mercs and enjoy being the best/ only real champion in the game.
