How Custom Loadouts could have worked

It’s so simple and haloistic:

EVERYONE GETS THE SAME STUFF! EVERYONE IS EQUAL!!!

If everyone could access the entire loadout system at SR-1, CSR would actually have an impact.

Primary Weapons: Remove DMR from this list.
Secondary Weapons: Should only be magnum.
AAs: Fine
Nades: Should only be frag.
Perks: DON’T WORK WITH HALO. You can’t tell what perk they have, even if it is used.

Yes, that’s a restrictive list. But it encourages teamwork. If I spawn with a LightRifle, I can support my short range bro with a carbine.

This should be in Halo 5.
