What absolutely needs to be changed if they want to keep the damage output from fireteam is completely remove parrying. As of this time there’s absolutely no downfall to parrying and the knife does stupid amounts of damage to the predator, taking about 15% worth of health off each swipe which effectively kills the predator almost instantly with other members firing on him.
That and half the time your attacks don’t connect, it doesn’t leave you with much options because the ranged attacks (other than the shoulder plasma caster) aren’t exactly the greatest at damage output.
