Falcon is one of those characters when you are not reading him you are like meh but anytime I actually read him in something I like him a lot.
As for his powerset I think its boring in the sense that he has not evolved over time. He should have a ton of SHIELD devices and gadgets at his disposal. Maybe some metal wings and some offensive weapons.
Now that I think about it I think it would be cool if Falcon served as the Avengers pilot (SOMEONE has to save them some money on Quinjets!) and their drone commander (which is militarizing the Avengers more then they need to be admittedly).
