Try RoL WS where black cat doesn't have abilities that can fail and see the difference there. You're using black cat in literally her best case scenario of a fight where the opponent has something that can fail on every hit and can still bleed.
And do it without relic as well
And do it without relic as well The relics were made for one reason and BWDO has the relic to, trust me is more easy to get a 3 star Black widow relic than a 7* BWDO dupped and high signature.
