New to rumble. early- mid or lategame champ?

Hi Frens,

Basicly title. i wanna learn some Rumble for cute competitive games but i always hear this champ is bad late and always wins early. My experience so far is that i can just chill early and be fine and get an insane midgame + lategame with a good R + Q combo. so what is he now? Is he all? is he none?
