This is something I've been thinking for a while about this game, something that IMO would make it a much better game.
So, to put it simply, I hope we get more "iconic" Lotr moments as player cards. What I mean by iconic is important images/scenes of the trilogy, as player cards in some form (we've gotten the beautiful Legacy of Númenor as a portrait of Orthanc). Because we know we're getting very few cards each saga expansion so we're not really getting player cards about everything that happens in that part of the book.. For example, the Argonath could make for some cool event (as well as location, I hope), something like "The Pillars of Kings" or "Sentinels of Númenor", which actually was a card in LOTR TCG: this one. That is a beautiful card iMO, and I don't really like to compare this game to past Lotr card games but this is more about being a good adaptation of Tolkien. One thing that past Lotr card games did right and so far much better than this game was portraying the world of Middle Earth and referencing the iconic events of the trilogy. And sure that was because the card pool was very much larger and they were based on the trilogy more than on the whole world (except for MECCG, that is an exceptional game in almost every way). I think it is essential to give a whole Middle Earth/Tolkien experience in a game. Since this game is so good at showing the hidden sort of history of Middle earth, which is great, it would be so perfect if it portrayed the more "traditional" elements and images a bit more as well, and I know that since it's based on the books it can surpass what the TCG did or even MECCG. And I know most of you will say "well, but that's what saga expansions are for." Yeah, no. Believe we're not getting much diversity nor quantity of player cards in TRD, we're getting a very strong specific theme developed in that one. Anyway, the main problem with this is of course the card pool size. Lotr TCG managed to make an insane number of expansions out of only 3 movies and some help from Weta, and it turned to be great. The solution IMO is to increase the player card pool, in whatever way they wish, but something to have more thematic room to explore everything Middle Earth has to offer player card wise.
