Its also a sideeffect of the european fauna only having a handful of really iconic species, so thouse that are are even more so.
Lets be honest, the red deer is very cool, beautiful and one of if Not the most imposing deer species, but if they would be living in africa they would just be another species of ungulant.
But that doesnt take away from the animal, but anhances them, especally as european wildlife is quite the mean and though bunch.
Europe is by far the continent most dominated by us humans and also for the longest time.
Any animal living here needed to directly compete with us, adapt to us and find a way to keep up with a radically changing world.
Ofcourse thats Not the only factor for why they are so resilient in the first place, but we still have red giant deer (thouse guys can reach the size of a medium sized horse), black beasts that are able to fight us 1vs1 and will if provocated, a Mix of very adaptable smal carnivores from all famillies and more.
Its a in comparison rather small amount of animals there are rather few/boring choices, which is also why its the dlc where i feel lile they can Do the keast wrong.
A pack of chamois, wildboar, european polecat and a marten might Not be what we are expecting, but i doubt that there would be much distain towards it, as every species is in its own way a mayor species and a great pick.
There are Not really alot of obvious misstep, as allmost every species has a point, which makes them a reasonable baseline inclusion
