I think he's talking about how the troops prioritize other troops when attacking, such as cc troops or skeleton traps.

Hurts Gowipe, but skeleton traps officially ended hog attacks on any halfway decently constructed th9 or 10. I liked having the option in war to hog through a base to save elixir, always seem to have a surplus of DE. Now it's the same attacks every war...gowipe/gowiwi or some loonion variation.
The solution to your issue is luring/taking out heroes. If the heroes are further out, send a golem/hero in to take care of one and lure the cc. Skeli traps alone arent strong enough to distract for very long. Many player are still 3 starring maxed bases in cw, but doing it using well thought out strategized attacks.

Watch the attack at 4:00 in this video, the attacker pulls cc and deals with it as well as the queen at the beginning of the raid. Needless to say it ended in 3 stars.
