This is just a suggestion for the pin attack when you hold right button i know it dosent effect creatures after a certain size but instead of pinning the bigger creatures it could just dig its claws in basicaly do a quick grab and do a quick bite.

Or instead of a bite like when it pins smaller creatures a claw slash where it just rips its claws down larger creatures doing some damage like bleed or something though not like the pin where it out rite kills them like with small creatures.

Its kinda like in the film even though its a film and this is a game where it kills those Apatosaurus or in jurassic world evolution when it gets in a fight against long necks it dose a big slash down there side killing them.

but instead it will just as said do bleed with a little damage and not kill them in one shot this is just so you can use it against big creatures not just small.
