Seeing the new move out of combat rules, I'm fairly confident CC armies just got their final nail in their coffin. Even if you can assault from transports and reserves and jump into new combats and continue, it still does not add up to the power to retreat after a single round of combat.
The only fix would be 24" assault moves for everyone, and since the attacker hits first, just gang up on one unit, then consolidate into the next and it would throw the pendulum far into the opposite direction.
Having any resemblance of balance under these rules will be nigh impossible.
Maybe that is the thing for GW, if they can't fix it, wreck it.
I was positive to 8th ed before these things came out, but now I just started to lean the other way.
