I have played through a bit of predator since the patch and I can say that I am fully happy with all of the changes made.
However I believe there is still work to be done when it comes to the smart disc, war club, and elder sword.
As for fireteam, I havent been beaten yet, but I also havent found a single team that is in the slightest communicating or spotting me, Which is unfortunate. But such is the way games like these work.
