lee got some funny tricks that can do with his combos and wards but u must be very carefull at teamfights because if they focus u you cant deal as much dmg as you should in the fight always come from the side and wait for your team to initiate then if you have a champion in your team like malphite or amumu who can jump on them quikly u must wait for them to engage on their adc or apc then you will safeguard on them and you can kill them quikly also your ulti can be game changing if you hit 4 or 3 ppl with your ultimate you can destroy their lane up. If you play Lee sin top lane with your ranked team tell them to take Orianna and j4 because they do a very good combo and u can easily win fights.
