Now you're getting it! Crucible is ment to be balanced so everybody can play it. That means averaging out gun damage based on Impact and Rate of Fire to make sure the Time To Kill is generally the same (hand cannons have a slow rate of fire, but deal massive damage. Auto Rifles deal less damage but fire faster, etc). Problem with The Last Word is actually perfect balance in my opinion due to the fact that it makes the gun able to push the guns effective range (it's ment for short-mid range) to long range too and can out perform guns that are supposed to work at longer ranges. If it can outgun guns that have a very high range from far away, when both it's perks and the guns design in general is based on short-mid range, there is a serious problem. It would do well to either take the Impact down a bit on the gun, or simply get rid of Perfect Balance so it can't be used to kill at extreme ranges as quickly as it can. It can be fired in full auto, but it should have a detriment for doing so which Perfect Balance negates.
