I think the main issue is that you can't use Mage Armor at all and gain benefit from it in wild shape.
I could be wrong but it looks like, when you look over the different shapes, even the ones that are "tank" shapes-
Their AC seem to have been balanced taking into account that you will use mage armor to get "good/decent" AC.
As it stands your AC will always be terrible. Perhaps not for the level 2-5 2-7 quests, if you pick the things that has OK ac.
But even their ac will be nothing while doing higher level things due to their base being so low, and your inability to raise it with mage armor.
