crap is what it is.
They havent sorted out the irvn, they have made jets useless against other jets, they have increased frequency of crashes(actual game crashes
), you no longer get put into a squad you have to hide and put yourself into one at the start, they have nerfed sniper rifles (bolts i think as thats all i use) as now they are mostly 2 shot kills in hardcore, they say theyve nerfed the g3 and scar, but i havent seen anything of the sort.
Theyve messed up with this patch badly. They still havent fixed the issues with campaign cutscenes and vsync where it makes it all stuttery.
they have however made it a bit more stable once your able to start up the mp.
These are my finding anyway.
