FPS's are different. Bullets fly faster than arrows. Its like someone shooting a rocket from a distance and you running for cover. You would have to lead with the rocket and also not have that person see you shoot it. The only thing you can compare a working aiming system is TERA to my knowlege. But that doesnt have first person view even those ESO you can scroll out to 3rd, It also is designed so that ranged classes can get out of melee range and CC. In what Elderscrolls game do you see quick paced movements. Just look how those characters run in the trailers.
