I like LoL and play it a lot, and I consider myself a fairly average player for the level I play at. However, while I know a lot about the game, I feel like I could understand it better. People often talk about good late game compositions and teams, and I know who some very good or very bad late game champs are, even aside from the obvious ones (Veigar, Nasus, Jax, etc). But why are these champions good ('these' being good late game champs. Not Veigar and Nasus. Those two are kinda obvious)? What makes a champion effective lategame, or ineffective?
Thanks for any help.
