Here are some more opinions on the last FP characters with at least 3 versions (I think).
Galadriel, Sorceress of the Hidden Land - Galadriel is the most banned character in the game so there was some stiff competition. The spot requirement is reasonable for a free character and the ability is fine, but it seems to me this level of devotion to Elves would be better served by
Bearer of Wisdom right? I dunno. I went back and forth between her and
Keeper of Nenya -- I use Keeper about as often as
Lady of the Golden Wood in post-Fellowship formats and I've seen her win games, but she does me wrong often enough that I'm a little bitter haha. If you WotR+ players say
SotHL is useful then I'll happily convert.
Elrond, Keeper of Vilya - I have fun with this guy in the one deck that uses him, but that's because there's really only one deck that can use him.
Celeborn, Lord of Lorien - The cards that he was best with got banned, so... Yeah.
Haldir, Elf of the Golden Wood - Jeez,
Warrior Messenger is the only version of Haldir that makes an attractive choice for a deck. Which is a real shame. This guy is bad in Fellowship block and outright useless outside of it, whereas the other guys are merely bad.
Orophin, Brother of Haldir -
Lorien Bowman is kinda useless outside of Fellowship block but so good in it that he eeks past Legolas Jr here.
Rumil, Brother of Haldir - Did someone at Decipher have something against Haldir? Just having him in the subtitle is apparently a black mark.
Treebeard, Oldest Living Thing - No surprise.
Denethor, Steward of the City - I think he's better than he looks, but yeah.
Isildur, Heir of Elendil -
Sword-bearer might have been worse but for the twilight cost. They're both fine choices though.
Madril, Ranger of Ithilien - Meh.
Gamling, Defender of the Hornburg - All Gamlings are really solid, I'm just bitter about horn decks
Outside of that this guy is a guaranteed
Simbelmyne which is great, I just don't know if I'm as willing to pay the twilight cost of a possession again to put it where I want. I think I'd still pick
Gamling, Warrior of Rohan over him. Probably controversial.
Hama, Northman - Even more specialized than
Doorward of Theoden and his text won't stop
The Pale Blade from tearing through your support area or
War Club from robbing you blind. They're both super niche though.
