I guess first Ruthless, it should be known that I am the author of this bog post and there is more, so be sure to click on more to read all of it...
As I stated in the article, there have been quite a few changes since I wrote this and we should see the changes at PAX. I will write a follow up after we get to PAX.
I will disagree with you on them taking modes that worked in MAG and redoing them for S4, remember MAG started as Socom, so it actually took everything from Socom.
As for the 2 min thing, it has nothing to do with respawn, it is just like having time to diffuse a bomb... only now if you stop the air strike, the attacking team can try again.
So with that being said, wait for part 2 after PAX...
