The game needs a big AI overhaul. It's not just hunting mechanics. If you have a herd of Triceratops and a Rex, only one Trike at a time will fight the Rex. It's painfull to watch. Herd defence and pack hunting are a must. That and more intra and inter-species interactions.
I was originally considering the limitations of what the hunting and fight system is. If they update does anything to change that system, then perhaps we could see something way beyond more my idea. I hope for that anyway. That kind of interaction would be amazing.
People often say the Compsognathus will act as a group instead of each being a unique individual. If that's the case, then perhaps they could implemente that mechanic to the other dinosaurs. But that would be a big stretch.
