“Balancing” is absolutely okay for the majority of matches.
It makes no sense to balance the game for the loudest minority in this forum: PC players playing as fireteam with friends.
If predators had a 50:50 win rate against such teams, other fireteams with random players would suffer alot.
To those PC players:
If you want to play with friends and want a challenge, play private matches. Switch the predator among your friends.
Regarding “balancing”:
Making changes each patch is normal for multiplayer games and keeps the experience fresh. As you know lots of games are not “balanced”. For instance, in many role-playing games certain builds are superior to others - depending on the patch. Often lots of weapons or skills are rather useless - just like in case of Predator: Hunting Grounds. So the “balancing” in Predator: Hunting Grounds is okay, i.e. average.
