It’s so people can make use of the new ability to get any previous mythic when completing the battle pass.

Orisa doesn’t have dedicated mains the way other heroes do. Nobody really relates to her and she’s only used as a response to enemy team comps (usually ones with high CC).

People don’t like playing her or playing against her. They chose the most filler hero with the blandest skin so people don’t feel bad about “skipping” her and getting a previous mythic lmao
