With how shallow-yet-deep WoW’s pet battling is, I think it comfortably invites changes of this magnitude, once in a blue moon- just like how Pokémon has introduced 3 types over the past 20 years (being Fairy, Dark, and Steel type).
I see more and more often an abundance of Battle Pets that begin to thematically feel a bit ill-fitted or shoehorned into something else just because they have to. With how many Pet families there are in the game, as many as 5 more could be added without disrupting the balance much at all. Though converting older Pets to their potential new types would be a tall order worthy of a major patch or expansion release.
IMO the new types that would be very well fit would be:
- Fel (for Fel pets that are objectively fel)
- Life (for pets that are druidic, life-magic based, or represent creation)
- Shadow (mainly for Void pets, or pets that don’t fit Magic, nor Undead)
- Light (for pets that are objectively light-based, or as a literal concept)
- Earth (for the new and old elementals, beasts, and critters that are more geology-based than animalistic)
(Additionally, all wind-based Elementals would be reassigned to Flying, all rock-based to Earth, all water-based to Aquatic, and the Elemental family would be renamed to Flame).
This idea mostly stems from examining the Warcraft Chronicles’ Cosmology chart, which has a lopsided distribution of pet families. All fel, light, and void based Pets are funnelled into “Magic”, despite Magic/Arcane being the polar opposite of those.
Life being a new type to contrast against Undead works as well for the abundance of beast, magic, and critter pets that are just put there because they’re animals, despite their life-magic movekits.
Just like Pokémon, this increased pet family count invites an immense amount of new family/ability combinations as well as more creative pets in the future that don’t need to bluntly be displaced into a family that doesn’t quite fit them.
A few examples off the top of my head of already existing pets that would be type changed:
Fel:
- All of the infernal, minfernal, shard of supremus, gill’dan, mischief, fel pup, piglet, spider, basilisk, fel stalker pup, etc
Shadow:
- Feline Familiar, Void reaver, Shadow, Twilight, the whispers of n’zoth pets, old god pets/tentacles, voidcallers, any of the Maw pets that aren’t undead, Lost Netherpup, etc
Light:
- Lightspawn, Sunny, Herald of Light, Soul of the Aspects, Spirit of Competition, any Naaru pets, Argi, Sunglow Cobra, Purity, some of the Bastion/Zereth Mortis pets, etc
Life:
- Yu’la, Daughter of Yu’lon, Night Fae/Ardenweald pets, Emerald Dream pets, fae dragon pets, Dream Whelpling, Murkastrasza, Jewelled Emerald Whelpling, a variety of Zereth Mortis pets, Marsh Fiddler, etc
Earth:
- plenty of Zaralek Cavern pets, earth elementals, shale-crawlers and deepholm pets, blackrock/dark iron themed pets, generic stone-based pets, or pets that use heavy earth-based influence.
Would be cool to see. Maybe one day! Thanks for reading.
