The first part of this post was already mentioned here. I’ve moved it into the spoiler below.
Many of you are already familiar with the Halo 5: Guardians update process. For those who don’t:
DO NOT OPEN YOUR REQ PACKS IMMEDIATELY AFTER THE UPDATE IF YOU WANT THE NEW REQS.
The Reqs come out a while after the update, and if you spend all of your req points before the reqs are available, you’ll just end up getting the regular stuff.
RP cost: The update brings 22 common/uncommom/rare items and 12 ultra-rare/legendary items. To get every req, you’ll need 11 silver packs and 6 gold packs, for a total cost of 115,000 RP.
Let me know if I’ve made any mistakes in my calculation.

Found it. I’m editing the OP to direct people to that thread. Thanks!
Thank you for this! RT to save a life.
Thank you, although I’m still dreaming of that Halo 2 BR. But, I’ve got 150k rp banked.
I have double the amount of req points needed. However I will keep in mind to wait since the reqs will come out in a few hours so I’ll be careful about spending any req points.
