The stun mechanic is frustrating. See: The crystal-powered Kulu at the start of the Behemoth quest chain. It has this great move where he stuns you in place, jumps back, then jumps forward smashing your face with the crystal. Insta-cart. A friend of mine nearly uninstalled the game because of how frustrating it was.
That pink rathian is always there on legiana investigations. Funtimes when the basil gets in on the action too. LOL. Pack more poo ; )
