How do you guys look at data?

I was talking with a friend about Urgots recent popularity, particularly in the LCS, which I think has given rise to his winrate. Now that people have seen how Urgot is supposed to be played they can now emulate these technique/build(s)/skills. My friend rebuttled with the recent tweaks Rito gave to Urgot which was the precursor to his success. Who is right? How do you guys decipher the difference between these two? Is the LCS something you guys consider when examining a champion? What does a champions popularity mean regarding the identity/skill/OP-ness?

Love all that you do for your community Rito<3
