Pets are no longer affected by damage-dealing floor areas.
The key words there are floor areas. This in no way means AoE. They mean such things as electrified floors and... hmm, there's probably more examples, but generally it means floors that do damage whether or not an enemy is directly involved. They still take damage from AoE, the the kinds of AoE differ. I believe in a farther back patch they fixed it so pets couldn't die from most instant kill AoE like King Behemoth's meteor or Amon's Curtain Call.
