Li Xin wins because he gives your team side-lane pressure without needing constant babysitting. He can play the map, threaten towers, and still arrive for objectives if you manage waves early. The trap is treating him like a permanent 1v5 hero. Good Li Xin players make the enemy answer side waves; bad Li Xin players disappear from every Tyrant fight.
