This quest is too hard in true solo. States difficulty 6 but it feels so much tougher.
I've played with an elrond/Gandalf/Galadriel three rings turtle deck that I beat the previous two quests. this quest smacked me around.
Then I tried an eagles grimbeorn deck. Then tried eagles with borimir and legolas.
Then I tried an Argalad Damrod mirlonde trap deck trying to pin down the enemies.
Then I tried two handed solo with the traps deck and the eagles deck.
In all cases I'm swarmed by tough enemies or locked with locations. The enemies also add to the orc assault objective when they engage or with abilities and some shadow effects.
I feel I'd have half a chance if the progress was removed from goblins assault between quest stages but it isn't.
Has anybody beaten this quest in true solo? Any ideas of the type of deck I should be building? (I have 3 cores and all expansions released.)
