I’ve seen the community split in half between wanting a predator hunts prey game, and what we have now. So why not make a game mode that allows the predator to hunt the fire team, who says you can’t please everyone?
I wouldn’t suggest making the fireteam or predator any stronger nor weaker, simply move evac time to end of match, change fireteam objectives to force the fireteam to separate and keep them moving and working towards their escape as they rely on their team and Whitts to succeed. You could add the trap that Arnold built to trap the predator in the first movie for the fireteam to use.
