i think it would be really nice for ranked if everyone could just play their favorite roles thoteambuilder's not for that imo.
like if i'm playing teambuilder i really don't care enough to be countering the other team's picks. i just want to play a specific champion for fun or for practice.
everyone could focus on composition and synergies and shit rather than who called mid first
also if i have teambuilder in all modes i would never have to jungle ever again
