Hey!
I just got back to the game last week after about five years of hiatus, but in the time I was not active the handful of games I played was with a very similar fellowship, also I think that I used this fellowship the most
.
Take everything I say with a grain of salt though, because I only played until the release of Bloodlines, and I'm sure that the metagame has changed a lot since then.
So, in my experience, the week spot was always Merry, he often got eaten up by a
Gorgoroth Assassin or
Between Nazgul and Prey or something similar, and my backup plan for such situations was to switch into tank style. For example I had Théoden, TAP in my starting fellowship in the place of Éomer, and I played 2
Riders of the Mark, a
Rohirrim Army, and a Gamling, DOH. One copy of
Cliffs of Emyn Muil can be lifesaver too for him.
Rohirrim Helm can be extremely useful too imo, because sometimes you can only take down bigger minions to 1 vitality (because of wound preventation or other reasons).
Also I tried the
Merry's Sword /
Sword Rack combo, and I was not convinced by it, but who knows... you may eventually end up with a different conclusion if you try it.
