Plenty of people have complained about the lack of diagonal aiming. Even reviewers that enjoy the game mentioned it.
Its absolutely not a "non-issue" my entire time playing the game all I kept saying to myself is
"why the fukk can't I aim diagonally
"
shyts frustrating and a cheap "mechanic" used to add difficulty where there is none. Had they added diagonal aiming they would have had to come up with some better A.I. And level design. As it stands the challenge in the game revolves around fighting the control limitations purposely put in the game.
