Who is your Worlds MVP caster?

Casters add another entertaining and informative aspect to pro matches imo. Who is your favorite caster and why?

It's tough for me, but i think I'm actually gonna have to go with Deficio. He gets an unusually high amount of hate. But I think he has great game sense and often knows these little random bits of information (for example, Trynd is a late game counter to Fiora). He just seems to have a very deep knowledge of the game, and he never comes across as egotistical. Just enjoy his casting in general, but I probably place a higher value on knowledge than entertainment.

Honorable mentions of Quickshot (positively contagious cheer), DoA (most entertaining imo), & Monte (pretty honest and direct with his commentary. great analyses even though he can seem biased.) RIP Joe Miller.

so, if you are interested, id like to hear some opinions and appreciation of you favorite/preferred casters! Not really looking for least favorite casters nor criticisms of any caster.
