I think they should implement some kind of trap system (cable based, or mines that do a decent amount of damage) that become available to the last one or two surviving members of the fireteam, so they can have a higher chance to beat the predator. This would also make the predator doubt about going ham in this situation.
This kind of traps would add variety to the gameplay and turn the end of some matches into a situation like Predator 1 movie ending.
