True, but at the same time, he doesn't seem the type to want to be a tyrant, forcing them into what he wants, how he wants, when he wants, with an iron fist; as evidenced from the previous(?) chapter where he emphasized to Estelle that just because he believed a specific build was the strongest didn't necessarily mean it was best for her and left the decision to her.
If he starts going drill sergeant nasty on them, it'd build resentment, of course, but it also wouldn't really foster comradery between the party members; by guiding them, but letting them figure out the finer details themselves, their cohesion as a team will only grow stronger.
At least, that's my takeaway from it.
