On my
mid i've been going fleet footwork w/ resolve secondary for bone plating and second wind, with dorans shield start its great against poke and bone plating helps me win trades especially against assassins or mages trying to be too greedy w/ their runes (domination/sorc eg.).
Its as it should be a solid defensive choice for surviving early that gets outscaled later in the game by offensive choices like ultimate hat and gathering storm, plus once people have damage even at 1 full item the defense it provides is considerably less significant except in small trades.
Plus you can easily poke bone plating off w/ a ranged auto or skill, back off for a couple seconds and boom its on like a 15 second cooldown.
