And A LOT of them. If they are aquatic so be it, but I think we need a bunch of them. 5 to 10 uniques, legendaries to match.
Make these dinos good. Make people have to choose which direction to go, a la tuoramoloch or diorajasaur.
Give secodontosaurus and concavenator 3 uniques each. Make them all strong/relevant. Make us choose which direction to go. (Most have a lot of these so it won’t take to long to get the dino you choose to team level)
We need diversification in lineups. And I think if there were more dinos and people had to decide which of the two or three or four hybrids to create, we would have many different rosters and a lot more fun.
