The lessons were pretty wrong.
"People can change!" Um, yeah, that sure worked out well with Garrosh now didn't it?
"Stop fighting!" How'd that work out for the Vale of Eternal Blossoms again?
"Fighting makes you stronger!" Uh, isn't this contradictory with the point above? Also still confused on how it makes us stronger. Does getting in a fight and having my arm broken make me stronger?
I wouldn't have as big of a problem with them being wrong if they weren't presented in game as 100% right and wise. I have the same problems with Anduin.
