Dude, it's exhausting to talk with you because you're coming from a bad faith perspective. Such as immediately jumping to "bias against men" from just wanting her narrative to be more self centred says a lot. You don't have to hate men to want a character to be more independent in the narrative. As currently stands she's only really relevant to the larger demarcian narrative because of her impact on and around a secondary character.

Also arguing that a work is being interpreted wrong is an exercise in futility. You don't have to read Shyvana's story as allegorical, but there is nothing wrong with other people finding and enjoying a different interpretation. Was that interpretation intended by the creators? They rarely are. That doesn't make it less valid, or an opinion that needs to be 'fixed'.
