Rangefinder is far too powerful on hand cannons due to how much they benefit from zoom. Rangefinder not only throws the damage falloff past where hand cannons should be, but it also makes hand cannons even more braindead easy than what they are. Hand cannons benefit immensely from the extra bullet magnetism at longer ranges you obtain due to the increased zoom value. Rangefinder hand cannons throughout Destiny 2 history have always been top dog by a mile and have noxiously outperformed exotics like Ace of Spades. Hand cannons like Dire Promise, Spare Rations, and Palindrome are prime offenders.
