I would easily take 4 with a compensation of reducing the capacity to 12 rounds. It does decent damage, but the five required rounds is a bit much. In PvE, most things die before five shots unless it has a shield or is a major, and PvP, most players die in five shots, precision or otherwise, making the explosion kind of pointless under most circumstances. And I get it's a Gambit weapon, but putting all that time and effort into a weapon only to be used on literally one kind of enemy in very specific circumstances is such a waste. Even with the boost to Taken, it's still too much of a novelty item, imo. We really need less novelty exotics and more useful ones.
