Great for laning and ganking. Not the best in team fights but makes up for it with ur damage. Aim for AP carries first in team fights. Great tower pusher and can jungle when needed for buffs. Keep in mind to never over commit with Yi due to the fact that hes raher squishy. In some cases u can switch out a thirster for Force Of Nature for magic resist if needed. Also if your taking alot of basis attack damage don't hesitate to pick up a thornmail. The longer your alive the longer you can devastate the opposing team.
