Does Rolling Help?
I've found that rolling helps a little bit, but when you're in close combat with a good shooter online, rolling around like an idiot is only gonna keep you alive for about five seconds more so the shooter can finally get you in his crosshairs. If you want to make someone angry, though, rolling around is a good way to do it. Sometimes the shooter will just get too frustrated to want to shoot at you anymore. It's pretty funny actually.
