Help me buy a champ !!

I like champions who impact the game. Preferably Top and Mid lane. Although I'm open to junglers, I'm not quite good at knowing when to gank and when to invade and pathing. Absolutely no ADC role based champs though because I just hate that role overall. I consider myself to be a very independent player and like to just carry games without communicating. I don't mind communicating though. I currently play champions like fizz and akali both top lane and I love them. I have some BE and I'm currently looking for any other good top or mid laners. Please help :)
