PSA: You don't need to pick champions in off roles in ranked

Listen, unless you're a one trick, YOU DON'T HAVE TO PLAY A CHAMPION IN A DIFFERENT ROLE!!!(i mean in ranked) No, you don't need to play that full ap gragas support. No you don't need to play that kennen jg. No you don't need to play thresh adc. Please, there are plenty of champions that are viable in each role that ARE MEANT FOR THAT ROLE. So again, please, if you're gonna play ranked, you don't need to play champions in their off roles unless you're a 1 trick. Thank you.
