This is a build for mid lane. If you go top or bot your results won't be as good.
Your job as pudge is to gank bot and top from middle lane. Your hook and ult are your best allies. Please practice hooking moving targets as there is a slight delay between you clicking the spell and the hook actually reaching its target, especially if your lag is greater than 100ms.
Predicting where the enemy will be is the most useful skill you can have as pudge
