If you've ever gone for a skilling pet, you'll understand the torture of a grind that it is. One of the primary issues with this is that it can be confusing understanding what instances you can actually get the pets in (take Ivy at Edgeville bank for example, it was confirmed that the pet can't actually be obtained there).
For this, I'm suggesting skilling pets become universal to everywhere that xp in that skill can be gained. Being here since day one, I have NEVER seen the Runecrafting pet achieved by anybody. This could be due to the fact that the majority of players use RuneSpan over the conventional methods (and my assumption would be that the pet is unobtainable at RuneSpan). This update would avoid any confusion or wasted time on methods where pets can't actually be obtained.
Alongside this, I am suggesting the addition of additional pets for skills that are currently missing them. Off the top of my head, ones that could be included are as follows:
Phoenix (Wintertodt) - The Firemaking Pet.
Tangleroot - The Farming Pet.
Kingly Imp, Chinchompa, Herbi (Herbiboar) Some kind of Butterfly? - The Hunter Pet.
Giant Squirrel - The Agility Pet.
Rock Golem - Replace the model for Rocky with this because what even is Rocky?!
