The Alliance already became more interesting when Turalyon became King of Stormwind in all but name, with Alleria Windrunner at his side.
Whereas Anduin was an untested brat, Turalyon is a proven and capable administrator, who already oversaw the reconstruction of Stormwind as the Regent of a young Varian Wrynn.
Of course, we cannot forget about Alleria Windrunner, who proved her leadership skills when she spearheaded an elven expedition into Draenor and then rescued and took over the leadership of the Ren'dorei group. I am sure she has done her part in securing Stormwind.
With Turalyon as Regent (de-facto King) and Alleria as his chief advisor, Stormwind has entered into an age of peace and stability that has continued for several years after Shadowlands (timeskip of peace between Shadowlands and Dragonflight). We should consider this a major victory, for Stormwind in-universe (as the nation is currently in a period of unprecedented peace), and for us players who have been longing for more spotlight outside of the Wrynns. I expect to see a lot more Turalyon and Alleria in the future.
