I believe it would be a quality of life update if we were able to see damage numbers done to both the fireteam and predator. This would give a huge information boost to both teams as they can then formulate what plan of attack they should carry out after words. For example if I as the predator saw that I did 50 damage on a fireteam member I may be prompted to then engage them so I can secure a kill likewise on a fireteam if I see I did 100 damage or more and the predator flees i can either make the decision to chase or use this time to complete the objective knowing he has to heal.
