The first three powers in this set are up on the official site for preview. Even from the limited scope we've seen so far, the set looks to be interesting for players of the game, offering both healing and damage utility depending on whether you're targeting your allies or enemies. They've also laid out the plans for the unique advantages of the powers, which seem to tend toward area effects - allowing you to at once heal your allies and stun everything around them.
One of the common complaints about Champions Online at release was that it focused almost exclusively on solo play and there was little to no benefit to grouping. With powers that are designed so strongly around working with other players, it looks like Cryptic is focusing in on expanding the tools available to groups. If players can tear themselves away from crushing zombies for a bit, these new powers look like an interesting upgrade for the game.
