Since three specs have different last level for there max pet.

Would for example 50 spec Earth pets be superior to the 50 spec Air pets? Since last earth level is 48 and air is only 32?

Would the air pet kinda suck in paralyzing lvl 50 players? even with 50 spec since the pet level is only spec 32?

You need lvl 32 pets in earth and wind so they have max lvl at 50 and 25 in ice.
Higher earth pets run faster, higher ice pets i dont know what excatly advantage is

I've been looking for a thread to further explain the functioning and rules behind theurgpets, but have not found anything so far. I understand that the first earth pet spell may produce earth pets up to level 10. But I am not sure if there is any difference beyond that.

As a level 12 air Theurg, I do not see a great difference between sending earth pets (not at all specced) and air pets (specced)

will keep my eye on this thread
