Simple answer: Yes.
Darkness Unleashed expansion has the much needed deck thinning capability that is missing from Rise of Vigil. Also, Darkness Unleashed has Dark Energy Shards that are added to the center deck in addition to the Energy Shards. This increases the overall number of energy shards, and bring their ratio up to 1 energy shard per 4 center deck cards. With a better flow of energy into the center deck, you'll have more people with energy, and the overall fun factor will go up. Also, transformations add a new twist to the game, and force more tactical decisions when banishing from the center row.
