why halo 4 shouldn't have custom loadouts

Halo is a classic game but with the details i have just seen it seems to be turning into call of duty as there is custom loadouts and thing that make halo are change (for the worse) as halo is a game where everyone starts with the same good and the more experienced player will know where the better guns are but now unexperinced players will be able to get better weapon easily and this follows the same line as call of duty so please 343 dont let halo turn into a noob friendly game like cod let halo be halo.

Most people are going to choose the same things every map anyway.

BR/DMR=big maps
BR/AR=small-medium
AR(or BR)/Pistol=small

Not that i’m sure you can choose those weapons, im just trying to make a point.
