The commander led the Horde or the Alliance against the Iron Horde in Draenor, ultimately defeating Gul'dan.
The champion, the hero led the united armies of Suramar and the joint venture of all the elves against Nighthold, ultimately striking down Elisande and Gul'dan.
The champion, the hero, the supreme commander led the armies of Legionfall into the Tomb of Sargeras, while side by side with Illidan and Khadgar decided to follow fate's hand and get into the portal to face Kil'jaeden.

We hear our character being referred as champion, grandmaster, battlelord, highlord, you name it we get it, but there's plenty around holding what we have, what gives us the right to our title of "the best".
And this spoils the narrative.
I understand some people like being the hero, and I understand that given all that's been accomplished during the years it makes no sense for us to still be nobodies. But not being the single most important being on Azeroth would help, because we simply cannot be due to how the games' mechanics are made.
