Yeah, I adore Caitlyn's voice. I tried her out and thought I was going to hate the character. Expected her to be an annoying girly texan cowgirl kind of thing. As soon as I heard her talk I just fell in love with the character....except for her outfit, not so in love with that.
She reminds me of Judith Gibbins (Lara Croft in Tomb Raider 2 and 3) "No that's not right. Go back to the beginning and try again!", but I'm not convinced it's the same person.
I really want to know who did the voice of the Announcer too, it sounds so familiar to me.
Dear Riot, I too would love to see voice actor credits for the game!
