WowAce

In the previous versions, pets (and dragons) appeared on the right, and you could target them like always. Now, they appear on the places of people using the drakes, but if you click on them, you can't target. To target the drakes, you need to click on the frames of ppl riding it, And you can never tell who is who, cause it's not in order. I presume the same will apply to EoE.

2.0.60 Wrath

Uncheck "Toggle for vehicle" option in General/Layouts/General Tab if you dont want to switch players and vehicles.

Duplicated issue, important read at least last post here:

If you use clique or mouseover macros to target units, you cannot target players units converted in vehicles due to a blizzard bug.

In the Name status configuration you can  choose to display player names instead of vehicle names for pets and vehicles.

I came to report, I see Pomptime already did and I can confirm this is broken in EoE as well
