Just ban Varus until he's nerfed, then play the role yourself if you feel you can do a better job. Yeah every other role is definitely not as impactful mainly because if you lose lane 2/5 champs on your team are semi useless, but If Top laners can reach rank 1 in all the major regions (i.e., Tony Top, Rascal, Khan, Thal, TF Blade, etc.) then it isn't exactly the role that loses you games. Khan has a famous Quote back when Jayce was considered overpowered, stating, "the problem isn't Jayce, it's your fingers." Now I'm a top laner which is why I use the role as an example, but this goes for any role. In jungle? Abuse Kha'zix, go 25/0 and win games. in support? go bard with electrocute and ignite and ROAM. In Mid? Go Annie and hard farm and just one shot anything that approaches you. The game isn't in a perfect state and it probably never will be as long as riot keeps releasing new champions, but you have to take responsibility for every game to improve. But seriously Varus beats all if he's fed, just ban him lol.
