Nah BM has by far the lowest of lows among top tiers. And her all out was not even remotely impressive either.
So until either someone shows lower lows at the same rate she did, or goes all out and has a performance below hers, she'll continue to be my reference point for top tier status.
Kidd isn't sniffing top tiers.
She really doesn’t. Luffy one shot Kizaru twice. The amount of AP shown necessary to KO BM is nothing any of the current admirals have shown to be capable of. Not to mention she split the sky with Kaido while not a single admiral is confirmed to have CoC or even awakening for that matter.
And regardless of how weak you think Kidd is, he is a 3 billion berry pirate, the same bounty as a yonko and the admirals.
This doesn’t mean Kidd is as strong as Luffy or the admirals. But it does mean that he is the bare minimum you need to surpass in order to even qualify as a 3 billion berry man. Not counting the obvious gag character Buggy.
