Looking back on my post...was that just 10 short days ago? I've warmed up (no pun intended) to this roster considerably. While I still think it is a tad too ungulate heavy, I think overall the roster is either a great representative of the theme or a highly requested addition that fits the theme, in several cases both.
I changed out 3 habitat animals in my initial post, but I now think the Black Rhino and Addax are good additions. Still sticking with my take on the Damas Gazelle though, we really didn't need 2 African Antelopes in one pack, and would definitely have switched it out with the Secretary Bird or Hamadryas Baboon. Likely the Baboon since..well....the Secretary Bird is a bird...and we see how that's going.
So yeah, just one habitat animal change. The Viper looks great and I'm fine with it.
