Putting the tag problems, crashes and logistics/squad organization stuff aside, i reckon its a very positive thing.
It actually feels like warzone now. Many pople said that its non stop action like COD, well yes, everybody wanted to shoot all the people on the other side, ofcourse its gonna be loud. But with some time, things will iron out and it will be even more epic when you will "hear" complete silence.

Its the thing that PR always lacked, the infantry being there with all the assets, full scale assaults and little recon missions, it has everything with 128 players. Ofcourse smaller maps are more hecticc, but in insurgency thats cool, as some of the guys can stay back at the main and defend/fire from there.
