Okay, so... Let's prove you wrong.
We'll have a look at Carrot fighting abilities, including her eagerness to fight, which is very important in OP :
This is her very first appearance, and already we can tell that she's able to surprise an on his guard Zoro and that her electro is strong enough to hurt him a little. It's an important element because it showcase her abilities to us, reader, before we even know her name. Just from it, it's quite clear that Carrot is a)more than eager to take her enemies head-on (which isn't the case at all for Nami and Robin in the crew, so she's already a vastly different character than them both) b)posses the basic abilities to back it up.
Here, the important bit is Pedro's sentence. He knows where they are going, better than anyone else. He knows how dangerous a Yonko crew can be, especially Big Mom's. And of course, he vouch for Carrot, another testament to her abilities, which should easily place her among the Weak Trio in term of level, at the very least (for me, she's quite clearly a Mid Trio level fighter, possibly upper Mid-Trio even).
Here, we have another proof that she can be extremely aggressive compared to the other female Strawhats, and all the Weak Trio. Below is another example.
Here, we are getting her first fight on WCI. It's important because it both showcases her speed, talent when in battle (she can notice and evade her enemies with ease and apparently does so without CoO) :
Yes, she got defeated soundly by Brulee, but let's be gonest. Brulee's power is hax. She even managed to block Luffy's punch when mimicking him, and I highly doubt her normal body as the strength to punch as hard as base Luffy has. And yet, it took hours for Brulee to truly catch Carrot and Chopper, who both had chains and boulders already. And while it's not clear how exactly she managed it, Carrot managed to avoid being captured anyway, as seen here :
As a side note, see how easily she flip the pot which seems to be quite heavy, while she herself is in a precarious position.
And with just a little water, her Electro is able to One-Shot warriors like Randolph, which seems quite at ease fighting the Weak Trio as seen when he attacks Chopper and Nami and has to be stopped by Carrot earlier in this post.
Again, we see how fast she is - notice how far Diesel is able to get from the house in an instant and how easily she close the distance, without any sign of effort. Meanwhile, Chopper needs Monster Point to deal with one -albeit very big - opponent.
She was captured by Daifuku's genies however, which I think is important to point out, because he's still a veteran pirate, with a 300 millions berries bounty on his head, so it isn't too shameful - especially when it was obviously done to allow the Vinsmoke to shine a little in battle prowesses. Furthermore, we know that even Pedro was surprised by Oven's abilities, and Oven is the twin of Daifuku. Again, it isn't a great showing, but it's far from terrible in term of combat abilities.
And it didn't impede her eagerness to fight, as seen here :
And while she does get stomped by Katakuri he's a)one of the strongest pirates out there bar the Yonko themselves and b) not really that much worse to wear. Furthermore, Luffy clearly considers here a nakama -probably still a temporary one at that time, but he doesn't even add the usual "and" before her name, as he does when he has to include someone who isn't a nakama while calling names.
I won't include the Sulong form here, because it's a once every month card (even if, Knowing Oda, it wouldn't be surprising to have all the future huge fights happening during a full moon -and who knows... if Ener returns with some sort of moon technology, on which Vegapunk gets his hands, couldn't something happen to the Minks ? It wouldn't even surprise me, really).
To conclude, I'll repeat what i've said the last several chapters : Oda had the opportunity to separate her from the crew, by putting her back with the other Minks, as he had done since Wano started. He didn't. She is the only Minks coming with them. Shinobu is tagging along, sure. But unlike Carrot, we already know that Shinobu is next to useless in a fight, considering that she's afraid of weapons. And she's of Wano, as demonstrated how deeply she cares about overthrowing Orochi and Kaido before and her presence is a "link" for the Strawhats to remember about it.
Meanwhile, there is no reason for Carrot to be the sole Minks tagging alongside the crew - or even to be here, if it's just as a support character. A Red Scabbard would have worked just as well.
To conclude, haters like
@PeperLevi demonstrate that they aren't "extremely skillful in read and interpret" at all and just let their disdain for the character blind them. Carrot is distinct in character from all the Strawhats. Males, females, weak or strong. She is an incredibly fleshed out secondary character, far more than the likes of the Grand Fleet captains - and even some Supernovas at this point in the story. She has shown great fighting abilities, is extremely close to the crew and, most important of all...
Haters have no valuable argument to explain why she is tagging along with them during the Raid.
