Can’t add much to the discussion.
I agree with you: it’s Anduin.
My Alliance warrior would follow him no matter what.
It’s stated that he is wise beyond his years.
My Horde character would follow Saurfang.
Why ?
Because Anduin recognise him as a character that still holds Honor.
In fact that’s the only argument I have now.
Anduin is written by the writers, he is the king of Stormwind and he believes Saurfang has honor.
Continuing the discussion from Old lore Vs new lore:
That’s just my thoughts.
Cheers.
