You shouldn't talk about "proof" unless you can prove something. Sure, there are some, but few actually whine only about too low system reqs. You may want to think all those thousands of posts are about the GFX, and while I do agree it's silly to complain only about GFX, it is most certainly not the only thing downgraded and complained about in this game.
I think concidering the very first 2 posts, I proved it quite well, thank you. That said, basically all Ive heard are a smattering of graphics complaints, a TON of "NO DX11," a few crashes (that's legit... not being able to play what you bought svcks), and several people telling me a game ending bug happens... which once I saw the "fix" realized I had had as well... only to go right through without thinking about it... it clearly doesn't end your game if you think like a gamer... and your goal is to get to the end of the level.
You obviously like CoD style fun, but why take it for granted everyone else likes it, as it's completely different from FarCry and Crysis? I agree, C2 is fun DM MP, but we already have plenty of CoD clones and can easily see why some of Crysis fans would be disappointed.
Never played CoD.... but considering the fun for me is the use of the suit's powers, I dont think you are right here... sorry...
