When comparing the Captain & Lore-master at least in terms of Pets it's a night & day difference.
- Granted it's just myself but I went through Western King's Gondor, Shield Isles, Cape of Umbar, Umbar itself, and the Underground where I only used my Heralds a grand total of 5 times for Landscape Content.
Captain also had it's time to get a Sizeable Update in 2023 so we aren't likely to see any significant Captain + Herald/Archer Updates anytime soon when comparing Classes such as the Lore-master + Hunter, etc. which have been waiting a very long time for Updates.
That said something I honestly would like to see the Captain be more unique by having both the Herald & Archer being usable at the same time.
- A "Small Fellowship" basically being available for the Captain for various types of Content and both Pets adjusted to play decent role in the Captain's Playstyle.
That & having it where the Captain doesn't need to worry about their Pets, going "Solo" basically, akin to what we see with Red and not focusing on Brother Skills.
