FPS gameplay grew deeper after Doom. The lack of difficulty (as perceived by the author) cant come from the lack of depth.
Speaking of decline in the FPS genre going from Doom is nonsense. The author is probably a socalled RPGer who cant take it that, in some other genres, players who play games for the gameplay first (gamers) still influence the outcome and that they had their priorities right. They guaranteed that shooters' main focus remained the shooting act.
For so called RPGers, it's been a while that roleplaying games must be about everything but roleplaying. RPGs must be about combat, immersion, story, romances etc but not about roleplaying.
Tough news, that deviancy has not yet reached the FPS genre. FPS 's main focus remains the shooting act. Doom is a milestone in the history of FPS but not one signaling a decline.
FPS as a genre keeps progressing.
