I like to run new dungeons with Trust to get a handle on the mechanics before I run them with a real group, or if I don't want to wait for the DPS queue in the roulette.

This was especially true in EW, where the NPCs were integral to the story, and it made it feel more epic.

At the start of ShB, they seemed flawless in hitting the mechanics.

The AI seems to have changed so that the NPCs make more mistakes on mechanics, to the point that the group wipes. I wiped three times in one of the EW fights because the healer kept dying. I changed my party comp so that one of the DPS had a heal and completed it.

Anyone else notice this?
