After all the shit Law and Kid threw at her she wasn't even down at all. And their attacks were really good.
Being Yonko level/ a real solid top tier is really something different.
Yeah she was too strong to be allowed to do as she pleased and as such she was nerfed in every way possible.
Well Blackbeard has many goofy and stupid moments but he's still allowed to shine and show his true dangerosity many times.
The problems are that Oda does it far too much and too many times, in often completely ridiculous ways in addition of that, with Big Mom and that she gets too few moments of real hype and epicness compared to Kaido and Blackbeard.
Honnestly I'd largely prefer to see her and her crew and family fighting the marines or someone else not affiliated with Luffy, because it's just painfully obvious that she and her crew won't ever be able of showing their true strength against the Straw Hats and allies.
