It just feels so out of place that a Bosmer Warden in Valenwood calls upon a Cliff Racer, Shalk, and a Netch for support -- those creatures don't even exist there. A Wasp/Hawk/Eagle, Thunderbug/Hoarvor, and something like a Spriggan would make more sense because those are creatures that actually exist in the region.
Has there been any discussion about making Warden's Animal Companion skills line more than just a Morrowind-themed skill line? Sure, Warden happened to launch during the Morrowind chapter, but I don't see that as a reason for tying the two together. Necromancer doesn't appear to have any Elsweyr-themed skills.
