I don't know where you read that. Everything I've read and/or heard just said that hip fire is very reliable but ADS will still be more accurate. Can you post the article that you read that from?
well i read a review from someone who played it at pax and they said that hip fire was way to ridiculous. he/she said that hipfire was so accurate that there was no point in ADS. personally, i am very upset about this. obviously i dont think you should be l33t to play a shooter, but i still think you should develop *some* skill at it. this level of hip fire only provokes spray and pray, something i am against very much. tsk, if i seriously svck at driving games i dont play driving games and i dont expect devs to put something that will make me play at l33t level.
edit:
i found what i was mentioning:

they dont use the word "ridiculous" but you get the point.
p.s. can someone pm how it is that you put a link and replace it with a word that redirects you to that link? yes, im noobish with html
