Need help picking new main

Hi,

Last season i peaked d5 playing veigar like 90% of the time. I dont mind veig but I am open to find a new main because tbh I kinda forced him to get good with him. Here is my preferred playstyle:

Big impact late game Good teamfighter Mix of damage and tankiness

I dislike full tanks like malphite and sion and also dislike champs that fall off a bit like Jayce, panth, renekton etc

Any suggestions greatly appreciated
