The viewmodel when using centered crosshair is so weird that its basically impossible to use the view model slider without making weapons like the BR and Carbine look bad. The default, non-centered crosshair viewmodel is already animated for centered crosshair, it didnt need to be “adapted”
How do i know this?? Well, using Halo 2 vista centered crosshair option and then comparing it to the e3 2003 demo viewmodel, we can see that the e3 viewmodel and the default viewmodel are in the exact same position (e3 demo being more zoomed in, but its the same position), and in Halo 2 vista, compared to MCC, the view model never scales to the crosshair positions. Because of that, the default viewmodel, as i said, is already suited for centered crosshairs, Bungie just lowered the crosshair without making any changed to the viewmodel, a change they did in Halo 3 since it was designed with lowered crosshairs in mind.
343 needs to revert the centered viewmodels to their “default” non-centered position since, funny enough, thats how the models would actually look when using centered crosshairs, just like in the e3 demo and the Halo 2 vista screenshot that i found, so they can actually look good when trying to use the sliders
