Build more tanky, no melee champ can survive without supreme tankyness against a half witted team, going into the fray means being in range for everyone to attack.

Dueling is one of your strong suits. Get items like randuins or youmuu's to increase your unpredictability in duels, using the actives to their best ability.

They also work well in team fights, giving you damage output from youmuu active should you not get focused first, and randuin active to screw their damage, since you are already going to get up close and personal anyways, might as well debuff their friends too.
