She was centric in the sense that she was a plot driving force in many of the in game cinematics and being talked about throughout both War campaigns, the intent of the comment was to point out that she clearly didn’t “Dominate” the spotlight in BFA and Shadowlands as a member of the Horde, as Gigabear has stated.
Agreed about spending far more time working with Magni as a Horde. At this point if you’ve played the game it’s glaringly obvious that the Horde are shoe horned into questing with Alliance leaders far more often than the contrary. Jaina, Tyrande, Anduin, Magni. The level of what equates to forced in game interaction, is hardly precedented on a player by player basis.
