U might think "hm Shen cant be played whit a ap build" But im sure he can. He got a good burst eatch 3 sec + slow. He hits like 600 whit his q attack then he deals 500 whit a auto attack when lich bane procs + his passive (200 dmg) so it would be a combo on i gues up to 1k dmg an the first hit and 700-900 on the secund (after 3 sec). U see he can do dmg if he gets item to do it. He will be a bit like akali. Dash in hit real hard and then be hard to hit but dont take dmg self whit his shield i gues he could absorb 600 dmg. He will still be a good suport whit his ulti and taunt to save ppl / hold / control enemy.
