I find it interesting that this post can be neatly surmmised as 'deal with it'. More so because you didn't find these gaping errors in design and balance to be that troubling compared to the clearly unforgiveable design decision of having to kill a sentry turret to gain Ghost pro or some meta objective akin to this.
Still worse, you winge about having to kill someone 4 times to gain a SAM turret in a tight spot and conveniently neglect the fact that launchers are still in the game and are as effective as ever.
I'll happily concede to your point on sniper rifles, they're nerfed and wrongly so. But shotguns are very useful (and not to mention fun)) on certain maps, as are LMGs. I've also not come across this so-called incredible motion sensor that makes you impervious to attack. It seems no-one but you has realised quite how amazing it is. I look forward going 30-1 with it.
I'm also not ignorant to the fact that you've been persistently whinging about many of the game's design decisions in this thread since before it was even released. I can't help but think that you're determined not to like the game. That's fine, but feel free not to adorn your thoughts on the game with disingenuous and biased analysis of its design when comparing it to MW2, please.
'Deal with it' indeed.
