Bought one Silver pack once, due to hearing that one gets better loot if they buy it. Nope, just more armor, not a single Rare.
Bought the HCS pack, because why not (rather use those 80K REQ points for Silvers, after all). Was planning on buying five more, because Legendary... then I saw the description. 'Rare or Higher', and cosmetic unlocks only. While I could use that to clear the board of the aesthetic stuff... why would I do that when I can just buy Silver packs with REQs?
Should have been guaranteed Legendaries, because $10 for Rares? What? And not a single chance at Phaeton Certification?
...Now, Halo: Fleet Battles, on the other hand...
