This is a wonderous build for Robin, making him a strong and heavy hitter, able to leap in and to loads of damage, then escape over a wall and into the shadows. But be careful, this Robin will be very squishy and vulnerable early lane, so i would not suggest laning alone. Your kit will help you more with survivablilty, not damage output, so Will is not a very important resource, and it is best to save your skills for when you really need them. Try not to be wandering around the map alone until you are a viable threat to most of your enemy team.
