After talking to my friend about it , I think I know why many people have a strong dislike to Ghost . In previous Call of Duty games (WaW , CoD 4 and MW2 ) to be hidden from radar you had to give up Stopping Power , But in Black Ops you don't have to give up a MAJOR perk . And in my experience most people who are using Ghost have been camping , And when you are camping you don't need Lightweight , Scavenger or Hardline because you can just pick up another gun or wait for one more kill and if your camping why would you use a perk that increases Sprint speed ?
Stopping Power was a pretty helpful perk and trading that for stealth could mean an extra 1 or 2 bullets to kill someone . If from the start Ghost had been a Second Perk or Stopping Power had been in the game I think alot less people would be complaining about it (With the exception of people who complain for the sake of it)
I know that the Ghost argument is "Old News" but I want to hear your thoughts on why people dislike Ghost or other perks/weapons.
