Saying Wanda is now unrecognizable because she's been brown for 3 years ignores the reality of how she looked for 95% of her history. Skin tone is not the sole phenotype that defines a character's appearance. Brown Wanda is outwardly the same Wanda, just with melanin.
Because we prefer Wanda to actually be a brown Romani woman like she was stated to be in previous comics, but never coloured that way. She became unrecognisable, because ppl decided to move on from the whitewashing & embrace who she really is
