As most of you already know by now, mythic req packs were added for a limited time.
However, I believe that 343i could use this pack, along with its name, to be a permanent new req pack.
Now I don’t mean that it should give you just mythic weapons, I think that the mythic pack should give you only ultra rare and Legendary Items. These packs should asking not be available to buy, and should cost around 20000 req points to unlock. That way you don’t get a gold pack just to end up getting rare or uncommon stuff only.
