I'm not sure what people are claiming you 'balanced' this time around, but in the past, I'd have to say:
1) SOCOM
2) M249 SAW
3) The way the 'bulk' system is in general
And to be honest, I forgot if there were any other ones because I just don't care anymore.
I think everybody is just kinda miffed about the sounds.
The only 'problem' I have with the pack is the G36 red dot being misalligned. Sounds are a little 'meh' on some weapons, and I think you guys should've probably posted a 'call for help' for a sound designer instead of using old sounds...but, it's your call.
The 'balance' thing that we oh-so-depise is when you change things for the sake of the game, instead of keeping it as it would be in real life.
Basically, INF is in a paradox Beppo. Half of the people want a sim. The other half just want a FPS that is 'slightly more complex than your average FPS'. And to be frank, none of us really know where it's heading right now.
One of these days, you're going to have to state your official stance on that matter.
Personally, INF changed my life and how I viewed 'games'. It was the reason I bought another PC and the only computer game I've enjoyed in a long time.
It had such an impact on me because of the 'realism', not because of the 'gameplay'. The 'realism' was the 'gameplay' for me. However, some of us want it to be more realistic and get upset when things are 'balanced for gameplay'.
We're all as confused as you are.
If you don't like a demanding / critial audience of fans, then make INF the ultimate arcade game. We'll all leave.
