Well if someone already got this tip but heres 2 more tipz that i use.
1- Try and balence your team (meaning that you should have 2 AP 2AD and a tank, having no tank works but not that well)
2- Press TAB to see what the other team is, if your top as lets say Zed, and say they had a kennen top. Building MR would give you lane domination which means that his poke does less damage and if they have an AP jungler then you get a double bonus. If you are under the level of 10 and under then just skip this 2nd step. Stay fresh peeps
