We know from V-22 experience that Tiltrotors do have an Achilles Heel of sort when it comes to the "helicopter" side of business.....due to the very design of the machine.
Restating what has been said before.
The FLRAA had a requirement to operate at mission gross weight as a “helicopter” at a height of 6000’ and a temp of 95F. Something you admit the UH-60 couldn’t do. The winning selection has a rotor/engine configuration designed to meet this requirement.
As to the V-22, it was designed for the ship based sea level air assault mission.
