The WoL's Protagonist Archtype is "Silent Hero" guys.

He/She is the blank sleight that we cast our own personalties too.

I myself tend to project my own ideals and thoughts on to my Avatar and by extension feel the outrage, not, sorrow, and confusion that the (ironically vauge) facial expressions display.

IMO FF14 has done an extremely good job potraying the Silent Hero Archtype.
