One of the biggest arguments against the ridiculously addictive PvP Crucible mode is that a number of weapons are wildly over-powered, and surely the most ridiculously powerful one is the Fusion Rifle. Though there's a trade-off in that it takes a second or two to charge (depending on which one you have), and if you miss, your opponent will almost certainly get the upper hand, but it can reliably deliver one-shot kills from a close-to-medium distance. Much of the Destiny community has complained about this class of weapon in particular, and though it can be combated well by the shotgun (which also delivers one-shot kills at a close range), everyone's been infuriated by that one guy who charges his Fusion Rifle before turning the corner, so you don't even get a chance to fight back. Still, it's Bungie's fault above anyone else's, even if players are inevitably going to project their rage at the 12-year-old kid who trounced them.
