REQ and Multiplayer help?

I got Halo 5 in January. Since then I have bee unable to join a multiplayer game or open a "Gold Gift Pack" until I complete multiplayer games that I can't join. I am able to play other online games, so my internet isn't the problem. I get an error message
saying "Could not find a server that was suitable for all members of your fireteam" even though I am the only member of said fireteam. Did anyone else have this problem? And how did you fix it?

Halo 5 Premium Requisition packs Price?

IIRC the 14 REQ packs are not standard REQ packs. I think they're supposed to have a better chance of giving out high end cards, armour and such over the Gold ones, because they are calling them Premium REQ Packs.

 

Warzone REQ Bundle DLC Share not properly conveyed

My brother and I share our games and DLC through the Home feature and we both were expecting the REQ Bundle to share. There was no indication or heads up on it NOT sharable.

To our dismay, we were not able to do so. The DLC redeemed on his account, downloaded onto both XBOX Ones, and activated. The XBOX clearly showing it downloaded to my Xbox, but not allowing me to open or find.

Here is the store description:

• Game Description:Gear up for Warzone and Arena multiplayer with the Warzone REQ Bundle! The new REQ System provides players with an unprecedented amount of choice and strategy. Experience multiplayer with the Warzone REQ Bundle, 14 Premium REQ Packs. Amongst
  the highest-valued REQ Packs in the system, the bundle delivers randomized content in the form of unlockable weapons, armors, vehicles, and more. These packs provide a greater chance at unlocking some of the rarest REQ Cards available including Mythics - legendary
  items so rare, so storied, and so powerful that they can change the course of entire battles. Get ready for the next evolution of Halo combat with the Warzone REQ Bundle!* *Warzone REQ Bundle (includes 14 Premium Requisition Packs, with 2 releasing on a weekly
  basis) requires Halo 5: Guardians game, Xbox Live Gold membership (sold separately) and broadband internet; ISP fees apply. Online multiplayer requires Xbox Live Gold subscription (sold separately).
  

No where does it state that it's excluded from the DLC share feature. There is no disclaimer, there is no link to a TOS specific to this DLC, and our Limited Collector's Edition does not have a disclaimer anywhere.

I have contacted support and I've been told that I'll need to go ahead and buy the DLC for $25. I was told that the DLC is similar to Grand Theft Auto's Shark Cards (and similar DLC) in that they will not transfer to other accounts. I do not see the similarities
as they are able to be purchased multiple times, while this DLC is finite. You can only buy this DLC once.

I feel deceived that I cannot access this content although it's a one-time purchase and downloaded to my XBOX. The exclusion was not properly conveyed and I'd like to see if there is anything else I can do.
