Atm i am feeling like my early game suffers too much, most junglers outudel me and i can´t get ahead early. Lethal Tempo and some attackspeed help quite a lot to negate some of those weaknesses and are especially in early teamfights really helpful to get your ad onto your taregt. It also depends on the team comp, if the enemy has a lot of squishies, dark harvest is definitly worth picking up.
