support that your enemies give poke, abuse it in lane and gain lane pressure and gain vision, and do not take gank, in addition the enemy will take so much poke that he will have to go base and your adc will take advantage, let the adc take it xp alone is a good option
I believe you have to have a good wave control... always ward the map and keep an eye on the map.. a very good tip is to pull the wave and give good roamings. I hope I helped in some way friend! if you have a lot of gold advantages I advise you to distribute this advantage with the rest of the team!
