This is a good build to help carry your team. At LVL 18 you will be able to 1v2 easily. up to 1000 crit with about 2.3 attack speed, so you will kill fasttttttttttttttt. Stay back in the beginning, just get the XP and kill minions untill you are LVL 6, don't get to cocky or you will kill yourself, your ult doesnt last very long. try to use it in the beginning of a fight, so your opponent uses there good moves on it, and BE SURE to ult the people who NEED IT otherwise its a HUGE waste.
