57% of LoL champions available were picked at least ONCE in the Season 2 World Championships
(note that Khazix, Syndra, and Rengar were auto-banned as they were recent releases though they appear on the list)

It's because not all champions are viable at all times.
Ashe is a champion that is not that great in tournies, because other ADs offer better advantages.
Varus' Q is amazing but he has a very early Fall off in game.
Warwick isn't that great compared to other junglers(Skarner, Lee sin, Maokai/Malphite)
It's just in tournaments people understand how to counter and what champions are better when they're the first picks.
