I was playing singleplayer on the island, and I had my imprinting buff multiplier on 3. I had two raptors, the highest level was (pre tame) around 100. The offspring had 500% melee, around 1,000 health, after imprinting of course.
So, after leveling, it had 700% melee and around 2,000 health, and because of the attack speed, it could probably take on a high level rex. And it did more damage per hit than a tamed low level giga. Long story short, with a high level imprinted raptor, you can devastate almost anything, and what you can't kill you can outrun.
So,I had 4 raptors.I bred them and I ended up with 8 killing machines.All you need is 2 raptors (boy and girl) to make a pack.these are great meat collectors.⬆️ if raptors are useful.(fast,strong,etc.)
If your raptor is level 200+ then if you are careful you can easily kill level 50 Rex, you just have to lead it to a paracer or a diplo the Rex will attack the diplo and you can take it out from behind. people can get easy levels
