LF Silver and low Gold Mid and Jungle MAINS

looking specifically for MAINS at those roles, i play adc and i duo w/ a top laner but theres plenty of games where my lane gets camped p hard and if i have a jungler/ mid laner who can roam down to help w/ that would be great, id say im pretty good at ADC but i go on losing streaks cause team chooses bad champs or team doesnt know how to team fight properly.
