I haven't tried the CC dimension yet, but I've had great success in groups of 10 footsloggers with an exarch with Dual cats. What a fantastic unit. A pair of them working in tandem is wonderful, and they are usually accompanied by Eldrad. With Doom, that's a lot of dying, and all 3 units are at their best when they are in that 13-18" sweet spot. Hovering at that range, unloading (Guided?) Doomed shuricats, Mindwars, and/or Eld Storms is a wonderful thing.
I love that extra range on the shuricat. It means staying out of assault range against most units, and as for those jumpackers, well, just need to bring down the rest of the list's firepower on them.
I've focused mostly on staying out of assault, and as such, Bladestorm has not been needed, but I could see its effectiveness.
