I'm not necessarily disagreeing with PR and Olorin93 (and I've never played with more than 2 players)… but that having been said, why not combine two sets of appropriate encounter cards to create the encounter deck, especially for 4 players? The ratio of particular encounter cards to players would remain the same as if it were 2 players using one set of cards, wouldn't it? And wouldn't a deck constructed from two sets for three players approximate the ratio of a solo player vs. one set of encounter cards?)? If anything, it would reduce the amount of deck reshuffling and make good use of "wasted duplicates" of encounter cards when you buy several core sets.
Am I missing something obvious?
EDIT: I suppose you might need to make some minor tweaks to encounter decks if using two sets of encounter cards for 3/4 players games… for example, remove the duplicate of Nazgul of Dol Guldur if playing Escape from Dol Guldur?
EDIT 2: (after my second post): Then again, if in a 3-4 player you still have only one hero start the game as prisoner in Escape from Dol Guldur, then maybe you SHOULD have 2 Nazguls waiting to swoop down once the prisoner has been rescued.
