Add 4th ability to pet families missing them

Add 4th ability to pet families missing them
This idea/suggestion is Open. You can respond to ask questions or discuss the idea and either vote it up or down if you believe it should or should not be implemented, respectively. Popular suggestions and ideas will be considered by the development team to become reality in-game.
Proposal
Add 4th special abilities to pets that are missing them.
Justification
Many pets are not currently optimal because they don't have a 4th special, making them strictly worse than pets with access to one. Other servers have made these changes and it increases the viability of lesser used pets.
Motivation
A lot of pets are significantly worse than others, limiting the amount of viable pets.
  • The Amphavian family does not learn Defensive
  • The Amphibian family does not learn Defensive
  • The Ape family does not learn Claw
  • The Avian family does not learn Puncture
  • The Bunny family does not learn Puncture
  • The Canine family does not learn Flank
  • The Caprine family does not learn Puncture
  • The Insect family does not learn Damage Poison
  • The Flying Insect family does not learn Health Leech
  • The Rat family does not learn Disease
  • The Simian family does not learn Claw
  • The Theropod family does not learn Slash

    This list is of changes other servers have made to balance pets that are not used. Making these changes would increase the pool of viable pets and make more pets worth creating from bio-engineers,. There was a previous PV posted about this a couple years ago that seemed reasonably popular but wasn't implemented, I'd like to change that.
 
So in your long list every place it says "does not learn" you want to change to "can learn"?
I don't feel like that's a long list, but yes that would probably be simplest. All of those changes seem balanced. Most of them are just brought in line with basically the same pet with a different skin. If the devs are open to different changes I'd be fine with that too, but figured just using these was simpler and made the most sense.

Here's an example: The Flewt is a Flying Insect. It can learn Bite, Puncture, and Wind Buffet. These are the same abilities as the Bat and Nock family, except those can also learn Health Leech, meaning there is no reason to ever use a flying insect.
