I absolutely never fire from the hip...  I'm much more accurate using ironsight.

I think most people do zoom in. 

Yeah, I am a much slower player, I always bring up my sights and track my target before firing. I never really fire from the hip unless I am in the same room as the person, in really close-quarters.

I always aim now.  i use to fire from the hip in world at war though because it was just as accurate.

I use hipfire in CQC. Also - it's a must for bolt-action sniper rifle wielding recons to be viable in CQC. 'No-Scoping' in sniper lingo. Especially SMGs (engineer kit specific) are great for hipfire.

Almost always. hip fire at closer range, or sometimes no scoping dudes can be a help with a sniper to get a fast shot off, but yeah..I don't know anyone who doesn't primary sight fire.

Depends on range. If short-medium distances I start firing before bringing up the sights. In short, hipfire. Long, always scope.
