We know Marvel is full of derivatives and knockoffs in a comic-book universe that has a cast of tens of thousands, but when the super-powered population of the MCU numbers only a handful, you can't go around duplicating powers and skillsets. That's been one of the complaints that's loudly (and fairly) leveled at using War Machine. We sure don't need more Cap knockoffs like Patriot and US Agent and a host of others.
