Personality Through Gameplay

How do we show a champion's personality via gameplay? We can have VO lines, while attacking, taunting, laughing, when buying items, taking down turrets, buffs, dragon, and baron.

But what about dynamic VO lines? What about stuff that is said when the player has a breakthrough performance on Viktor? Does he taunt everyone that their lack of machine parts make them weak? What about Vel'koz when he doesn't get any kills? Does he complain about being hungry for knowledge, urging the player to "learn" more enemies?

During lulls in the game while the player (and team) is considering their next moves, dynamic VO lines can be played to guide the player towards a play style that closely matches that of the champion. Teemo will want to scout ahead, Lux will want to provide vision, and Rengar will want to hunt greater prey (enemy players who have more farm and kills).

Shout out to Ant in Oz and Jaredan. What do you guys think?
