Same, I started playing Ark early on because I wanted to play a survival game with dinosaurs. SE added zero new actual dinosaurs. Aberration introduced zero new dinosaurs. I was bummed when each new release would be a jellyfish, bird, sheep, or unicorn.
I get other people enjoy all the other stuff, and I'm not against it. Personally though, I just wanted to play a dinosaur game, which is 100% how it was advertised early on.
