When I finally leveled up and tamed strong dinos including 2 griffins, 2 gigas, and a titanosaur, I rounded up all 40 of my dinos, whistled for them to follow and attack, and then slaughtered every raptor I came across. I of course was happily stomping them all on my titanosaur and shooting rockets at them from the roof of my titanosaur base. It was a one sided slaughter. I even got 2 alpha raptors. REVENGE IS MINE!!!
