The Fal is an amazing rifle period. With SF enabled it does give it that I'm using a low end rapid fire controller feel to it. However, it is still at least 3 shots for a kill in my experience. It is super under powered considering in BO1 it was a 2 shot kill.Was my favorite in BO1 as well. The overpowered weapons are the pistols hands down! I took one from some jackass the other day after running out of crossbow bolts taking out a few snipers and collected 6 kills that were so iffy it was stupid. I mean seriously they "should" have been able to kill me and I said that when I got each kill. Literally, holy crap this thing is over powered, and WOW I actually nailed em!
Lag compensation in the game is one of the biggest problems with weapons feeling over powered I think. Some of them just miss because they are designed to miss X times at X range etc... (in my opinion anyway)
