4e Pack Lord: Whenever heroes kill one of its allies it can force one of them to hit themselves, it can move multiple allies forwards, grant them extra attacks
5e Pack Lord: Just regular Gnoll but can recharge one ally's Rampage.
Actually, it sounds like a great design choice, D&D has been way more focused on combat than regular rpg, and has never been the proper choice for roleplay, politics, horror, investigation story.
It seems that at least 4th edition was doing combat right
