PA needs babysitting at the beginning. Ask your teammate to pull creeps so that you can keep staying around the tower. Get LH as many as you can, and if ranged enemies show up on your lane, use Q skill to get LH. Don't push the lane until you get proper items (ex. battle fury). Stack ancient creeps using helm of dominator and get the creeps once you become LVL 12~13 (at least 3~4 stacks). 1-poor mans's shield , 2-phase boots, 3-morbid mask, 4-battle fury, 5-helm of dominator, 6-BKB, 7-basher.
