Personally, I think it was a good thing to create faster paced games, it made most weapons at least useable, and it was a SACRAFICE to give it up to use perks with similar effects to Ghost/Cold Blooded/Assassin. Now there's virtually no down side of those.
I'm hoping Black Ops 2 / CoD: Eclipse / Call of Duty 9 have it back.
Opinions? Try to think about it from a standpoint of balance. Even though it was almost necesary, it made users of cold-blooded balanced, but also more effective (Because it was more rare in MW2, therefore much less expected), because they had to sacrafice.
EDIT: This is my opinion, don't feel like you have to point out that you think I'm speaking for everyone. Thank you Nick42294 05:55, April 22, 2012 (UTC)
