Just got my Raptor yesterday, along with a Direwolf. Went out hunting with them, leveled them up got Gill a saddle. -(My Raptor) Then a Therezonasaur, or whatever you call it, popped out of nowhere, killed my Raptor, Direwolf, and me!
Get your bola ready BEFORE you enter agro range. These things hit fast and once they reach you they tend to zig zag to dodge your attacks. On mobile all wild raptors can pounce you leaving you defenceless which needs a nerf because it traumatizes noobs and makes raptors very dangerous. Add to that how common they are and theyre basically stopping you from progressing. On mobile if you run at them from their back they wont expect you and get agroed only when you are very close
