I recently played the play as dino mod as a Troodon, and I had a huge pack of Troodons. We were wreaking havock all over the south of the island, even killing a Theri at one point. However, do not tame them in the real game. It is not worth it. Sacrificing your tames just for a scouting dino isn't worth much. Maybe in a PVP setting, but I am a PVE player, making them worthless to me.
