Nah, they have other ways to replenish Mana. It just isn't as effective as a direct transfer.

Even if she isn't with him at the beginning, she will eventually track him down at some point.

He 'is' weak and usless. At least compared to literal Legendary Heroes and Gods...

Not necessarily. If they need Thomas, Astolfo can track him down within hours. If it's an emergency, she could even reach him in 'minutes.' In other words, she can fly over to Thomas with Caenis/Beni/Musashi/Atalanta/etc whenever she wants.

A bit of distance, if temporary, can bring people a lot closer. Thomas needs the opportunity to grow as a person. If he remains on the Hind, he'll almost always be in the shadow of his Heroic Spirits. After all, once they gain bounties and ascend, they'll become even stronger.

It's only temporary.

No. Even if you re-read, not even half the chapters mention how 'useless' he is. Saying 'most' is a gross overstatement to exemplify how you feel about the novel. Now that he's no longer in the shadow of his Servants, he'll be able to grow a lot more.

You're acting as if they will never meet again. Besides, Chiron already taught him the basics he needs to learn to master Reinforcement. At this point, it depends on Thomas to actually master it.

It's almost like she's a pirate that desires freedom and adventure xD...

This is literally the development that will allow him to grow as both a person and the main character xD...

That's why Drake wants him to leave. So he can grow into his own without living in their shadow.

It's almost like he's a relatively normal person surrounded by some of the greatest Heroes in history and literal Gods...

They might be Thomas's Servants, but the 'crew' is very clearly Drake's. There is a reason she's the Captain, at least until Paul is actually ready to command them.

All of Thomas's Servants have Independent Action except for Caenis. However, as mentioned by Drake and Chiron, they can replenish Mana by killing and accumulating belief/faith. Caenis can also draw Magical Energy from the Equivalence Engine, so being separated from Thomas for a year isn't a big deal.

It's more like he will be accompanying them during their travels through the first half of the Grand Line. If Thomas remained with the Wild Hunt, there would be no real tension. Most of his time would be spent training and planning his future actions rather than actually doing anything. This gives him a chance to grow organically while also pitting him against foes around his level.

Why sadge...?

How so?

No, you weren't. But that won't prevent you from saying whatever you please. Take care.
