I agree. Work on new animations for more social, hunting, fight kill, and guest kill animations.
Just focus on some of the big names of each category.
Large carnivore: Rex, Spino, Giga, acro, charca
Medium carnivore: sucho, bary, carno, cerata, allo, alberta
Small carnivores: raptor, denonichyus, herrera, dilo
Armored herbivore: trike, anky, styraco, gaganspino, stego
Large herbivore: brachi, apata, Camara
Non Armored herbivore: Para, Maia, Edmont, mutta, iguana,
That's 28 species. Pick some favorites and focus on them giving them 2 or 3 more animations on top of what they have.
Then u could focus on some more later.
