This is possibly the only dino that's still will be effective from the beginning to the end stage, these things have a pack buff that really isn't gonna do anything to bosses,, but historical we always learn outnumbering an enemy is a guaranteed win, get two raptors and breed them together till you have a gang of them, put points mostly in health stamina and melee damage and with the pack buff these freaking machines will start attacking nonstop even if one deals 40 damage their fast strikes kill even brontosauruses
