Mine would be "Ignition kills grant restoration stacks based on the rank and number of defeated enemies" to Gunpowder Gamble. The reason I was is because I was recently thinking about how class identity is well, gone, and I was thinking about a way to make Gunslinger Unique. That line of text would do wonders for the class. All the knives (except lightweight) become way more valuable and more fragment slots open up. It would really shake up the boring "throw down healing grenade - spam melee - repeat" gameplay loop.
