Changing Meta at Worlds

Last season, it looked to me like the basic idea in most games was for the jungler to gank mid and snowball mid then for the mid player to roam and win dragon and eventually win the game.

I think that XDG and FNC played this way.

This season there is much more team coordination and more teamfights than there were before.

I think it is a higher degree of skill that teams have to show, in all positions, to win now.
