Yes, thank you. That has been my point. We can agree that they didn't introduce these characters to show support. They are not there to show she can't do it alone. And for them to be introduced in that position makes them pointless to her story, because 'showing she's gone too far' can also be achieved by showing her hunt down Sauron alone, just as we see her at the end of the episode.
The company was absolutely pointless to her story. Whether they were there or not, she was still going to go hunt Sauron on her own. All other dialogue could have been done through her reflecting on flashback scenes. Mandalorian did this well, showing more and more of Din's past as he slips into memories when he falls asleep or gets rocked. Even some of the best parts of Book of Boba Fett were flashbacks.
The show didn't even need to introduce her leading a company and ending up on a boat to Valinor to establish this, they were already implied with her literally trekking into the north to find Sauron. In context of what we've seen of her party, it would have made zero difference if the other Elves were with her or not. They were only ever shown holding her back. They were as useful to her as the survivors on the raft sans Dude who Saved Her. Like, it could have literally been an empty raft and nothing would have been different other than the one scene where lightning conveniently strikes her pole and has her drowning just so dude-who-doesn't-care could save her
