The morale mechanic is one of the things that makes this game unique, those 2/1 creatures cost you 1 morale each, on a faction that is all about high damage, low health characters. The bigger guys cost you more morale, the smaller guys cost you less, that's natural. As a FD deck, you usually either win by the 10th turn, or you end up losing in the end, one way or another, as a WP deck you have a lot of big guys that get bigger and bigger, but cost you a lot of morale, and another thing is most mass removal is easily dodge-able. For decks like DoD, their entire goal is to block the damage and slowly wear you down in morale, in rise every deck is basically the same idea, with new ways to do it! Morale will always be a legitimate way to beat your opponent, but there will be more counters to morale loss in RISE and the set after RISE.
