Jinx is verry strong adc laner. She can poke and trap champions from enemy teams. Got much attack power, and later in the game much attack speed too. Its easy to overtake controll on the line with her. If ur going to build her like me, with same order i make here ur going to get much attack damage, attack speed and lifesteal. Thoose three things makes you usefull in all of situations. U can restore ur life in just few seconds. Fast tower destroys or damaging. Dealing much injuries to the enemy teams and easy to get kills. In late game with full build: - Verry easy to kill (most in TF) - Fast towers destructions/damaging -Easy to poke enemy with good damage In early game: - Easy to farm -Getting controll over the line -Poking enemy -Traping enemy This is just few of all positive things she can do.
