You are dang right about earning customizations. I want every piece of customiaztion to be tied to a specific achievement like they did in MCC. My two customizable options I am most proud of are the Achilles helmet and the blue skulls emblem in MCC for beating CE on laso. I had to work HARD for those and I’m proud to show them off now. Couldn’t give a rats behind about any of the stuff I unlocked from req packs
Sound's like you're getting mixed up there, Achilles was a bit of a grind for Halo 5, not MCC. This is the list.
Helioskull was for beating Halo on legendary in MCC. Not a fan of the REQ's either since it took me forever to get my classic armour legit then 343i kept giving it away. :/
The REQ needs to be gone, Warzone Assault is mostly unplayable because of it, if Warzone ever returned it would never a major overhaul since the REQ was an unbalanced mess. What they should have done is just make BTB with possible AI while completely removing the whole REQ system from the game.
