to everyone who say "X" champ is op becuase of worlds
im sorry.. your wrong... maybe they are op.. maybe they arn't
but using "worlds" as your data point is stupid
first point "X" champ is always banned
well lets see everyone always banned
vs huhi..
well ROX in the infinite wisdom.. decided NOT to. i dont think they will be making that mistake again
these teams KNOW who they are facing.. they can TARGET bans..
froggen isn't goign to get
smeb isn't going to get
again
huhi isn't going to get 
next point "X" champ has a "really high winrate in worlds" ok.. whats your point. your taking a sample size of HOW MANY games?
"next point" "X champ has really high % pick/ban rate"
ok.. well how strong has that champ been doing this year? is it a role has has a role of picks to choose from?
and lastly.. does this reflect what your saw in the LCS leading to this.
for example.. nidalee has a 100% pick/ban rate in worlds.
well that the start of the summer split nidalee ALSO had a huge pick/ ban rate
you wanna guess what her pick ban rate was at the END.. NOT VERY HIGH
but guess what.. EVERY jungler in worlds how to play her now..
