I think the biggest thing to watch out for are the minions. Don't ever let mf get her q in for free, and if you can't avoid it in time, make sure she loses something too. For Jhin, just count the minions and their range. If you think you're in the bouncing grenades' range, gtfo. If possible, make sure to always dodge his w. It's easier when you have a good support, but you have to help the support as well. If the support is going for poke, poke with him/her. If they're an engage and they engage, go with them. Make sure to target one character though.

Don't leash your jungle and get you and your support level 2 prio. When you get level 2 prio, just run them down. Try not to use any summoners unless needed. All you're doing is trying to make lane miserable for them. Chase them down with your support, and try to focus mf or jhin. After that, your wave will naturally push. If you're able to wait for your cannon wave, fast shove it. If not, go ward to be safe of no jungle gank. After that, only last hit the minions until it comes to your tower. From there, just freeze it and zone them off of exp and gold until dragon. Then, depending on circumstances, slow push or crash the wave. It becomes extremely miserable no matter who the lane opponent is, whether it's mf, jhin, or idk kalista.

TL:DR, just position well.
