I am actually really proud of our live balance team. Not only were 66 different champions picked, but of the ~40 not played, a large number fit into the following categories:
Clearly tournament viable but just not used (e.g., Kayle, J4, Singed, Hecarim, Sivir, Udyr);
Niche picks that never had a use-case in this event (e.g., Fizz),
Lesser used champs whose players got were either not in attendance or were knocked out early (e.g., Kassadin, Fiddlesticks, Swain); and
Potential breakout stars that none of us would be surprised seeing competitively in a month's time (e.g., Varus, Wu Kong, Syndra).
Less than half the champions available were used/banned in IPL 5

Major props to the Live team.
i would be very surprised to see a wu or syndra in a tourny in a months time unless there were buffs to them.
*Swain was used at Worlds, I think by Invictus Gaming(?).
*Wu Kong can dominate a lot of midlane/mage matchups and, coming out of top, might be the single best Champion to put an Orianna ball on.
*I don't think any of us can really assess Syndra's power level right now. Her potential is off the charts though.
