Anduin's story arc is this:
He's a little kid standing next to Bolvar & Onyxia (Lady Katrana Prestor) because his father is MIA & Bolvar is his guardian/advisor - de facto leader of Stormwind & the Alliance until Varian returns/Anduin comes of age.
Varian has returned, Anduin doesn't want to be a Warrior. Gets Jaina to help him convince his dad to let him learn about the Light from Velen. Goes off to the Exodar.
Is older now, reluctantly learning swordplay but still pretty sure he wants to be a clothie. If Tirion & Bolvar hadn't been away, he probably would have learned how to be a holy warrior from one or both of them.
Yikes, dragon!
Is nearly a man & doesn't want to be tied to Daddy's... Ponytail anymore. Runs off to Pandaria & gets in all sorts of trouble including nearly getting himself killed. Still doesn't want to go home but agrees perhaps some more training is in order.
Everyone went to Draenor.
Oh crap, now I am King. Identity crisis. Worries that the people will think he is unworthy to be king. Wants to see where Father died saving everyone else. Regains Shalamayne. Gains a little understanding & a lot of resolve.
Sylvanas, you are EVIL! FOR THE ALLIANCE!
Sooooo yeah. What exactly could we create a statue of at this point? He's just barely now DOING something in the game.
