Split push on fizz. you should be doing it anyways. I used to see this a lot on mid laners in lower elo, plat 3 and below, adcs as well. Basically, you got to train yourself to get out of mid, quit running it down every game. Its a different thing to just push to river on say orianna, but, with these mobile mid laners like leblanc, ahri, fizz, corki, ekko, and such go use it to pressure lanes. Your top laner won't say it but, it will help a lot to setup picks, taking soft towers, generally running them around the map. That will help you snowball, and snowball harder than you previously did. It can take a bit to get used to split pushing on a mid laner, so ya, you will get caught a lot. Keep at it though and things will start to make sense, then, it will be pretty rare at that point getting caught, or when you wanna get caught for a 2v1 fight attempt and such. You will figure it out with practice and some other things like trading your life for say a tower and a kill, usually worth.
