What happens when you take a species out of its natural habitat where it has a predator? It thrives. Out of all playable races, Vulpera is the only one that reproduces in litters. For every human, draenei, elf, goblin, gnome, tauren children, we vulpera produce 3 to 4 babies. Fast forward a couple of years and we will be forming the bulk of the horde army. So what we´re seeing in game regarding player behavior (3 vulpera in every leveling dungeon with only 2 members of other species) is what would happen IRL with our explosive growth. So what are the Vulpera for the horde? Not only a cutesy, survival race with capability to live in harsh environments: we´re also massive reinforcements. Vulpera warriors are vicious, agile, need little food to perform at peak capacity and are mass produced.
So while the alliance got the technological edge in BFA with mechagnomes, the Horde got the numbers. Our arrows will blot out the sun.
You are forgetting one big thing though about Mechagnomes. They can replicate themselves on the fly. Each 1 mechagnome counts for 12 since according to that one rustbolt quest they can make about 12 replications of themselves on the fly.
So far I’ve seen like maybe three Vulpera kids. I don’t think they have litters like you seem to think. Just because they are based on foxes, doesn’t mean they reproduce like them.
