Early game should be fun if you have a good support. Having a good support will get you fed. Stick in the bushes and be aggressive and try to take out the bot turret within 5-10 mins. keep an eye on the jungle so you don't get ganked. Head back to base only if you absolutely need too. After you take out your first turret move to either mid or top to help take out their turret. Keep pressure on the enemy team cause jinx is good when the other team panics and starts to fumble around. Late game when it comes to team fights keep a good distance and if you or a teammate is being chased drop some flame chompers to help escape. With high attack speed and damage you will burn threw the enemies health and if you are at a good distance you should not be killed unless they wipe your team and slow you. Lastly, the item set gives you big boost to attack speed/attack damage and crit chance. Also you get life steal (which helps keep you alive in most fights) and armor penetration which will help late game. The item that helps the most is the statikk shiv because when it comes to team fights it allows you to damage 4 enemies at once and the frequency of that ability activating is increased with the increased attack speed.
