LoL metagame 2015 for noobs
Just asking, as I am a noob and would like to know more, how does the metagame work in** LoL?** I know what ganking and laning is, endgame etc., kind of what tanks are, but I need a little more info on what ADs are and specifically which type of player goes where in the lanes/jungle. (Specifically in PvP 5v5 Summoner's Rift.) Thanks!
