Basically what you want to do is have as much attack speed as possible. Having Daedalus will make your attacks worthwhile... If you role this, I recommend going mid. Use sacred arrow often and make sure you are a decent distance away for the extra damage, trust me sacred arrow at low level with the extra damage is basically a 2-3 hit depending on the hero you are fighting. My tactic is simple; Sacred arrow, If it hits immediately leap to them, UNLESS there are other heroes. If they are alone.. do it.
