Just beat it second attempt but just barely. I don't find it overly easy so far, somewhat challenging in fact.
The locations pile up super quickly and without player cards that help against locations you are more or less screwed unless you can generate very high willpower quickly. Also if you don't kill the Marsh Dweller on stage 3 (I had it on 2 hitpoints....) its resource tokens remain on stage 4 and it is a much more formidable threat. I had it at 8 attack strength and also had it reveal TWO shadow cards that cause an additional attack during its forced attacks as part of quest stage 4A. I cancelled one with a Hasty Stroke and lost 3 chumps... (the exact amount of ready allies I had available). I then used a Feigned Voices on it during the combat phase to stop it attacking and killed it in one hit with Legolas (Bow of Galadhrim), Haldir (2 Dunedain Marks, Rivendell Blade, Bow of Galadrim) and Elrohir who had a combined attack of 15 (It was engaged with tactics/leadership so +2 to Haldir from the bow and +1 to Legoals from his). I may have smashed the Marsh Dweller fairly easily (and the other two enemies are fairly easy, did not have one survive the round it was revealed and no ill effects triggered on either attempt I had) and lost the first game mainly due to location lock but the Marsh Dweller is no joke and the quest overall seems difficult enough to me for an AP halfway through a cycle. It isn't the terribly last hard one or fairly hard second last one or one of the first two which are normally fairly easy.
Had a very fun time playing it and will definitely return to this one to get a better score, experience the other quest stages (some seem much harder than others) and simply because it was a well designed, challenging and fun quest. Definitely harder than Trouble in Tharbad and The Three Trials (for my decks and play style at least) but easier than the Dunland Trap, To Catch an Orc or The Fords of Isen.
