but aside of this you must(very important): ward suspicious bushes,and not facechecking them, improve your map awareness, use pings to alert your team(bronze players have really low map awareness,no offense if you are one), think about that game,think a strategy,do not walk like a mindless fly waiting for someone elso to do this,cause he wont, choose 2 roles and master them with 2 champs each(2 champs for (your role),and 2 champs for (your role), and focus on destroying their base
there is also a order of importance here in lol here it it: nexus>inhibitor>push>kills( i think its in that order)
anyway i think i covered the most of it,so GL in your season 8 rankings!
