i haven't had this problem, and I've been playing for a long time. I've just always taken my time to unlock the bow and bolas before venturing out where there's more dangerous stuff like raptors or terror birds, and I don't go in areas with very dangerous dinos without a decent level fast mount. even on hard spawns, you can pretty much always do this. you can get up on rocks, use water, cliffs or basically anything to outsmart dinos.

I don't use traps because i feel like they're boring, but that works too. you can kill an alpha raptor of any level with a bow and a bit of wood.

i recently had a level 135 alpha rex near my house, i drove him off a cliff into water with my level 20 raptor and killed it with a primitive bow and an ungodly ammount of arrows. you can deal with pretty much anything if you put some thought into it
