The biggest problem when it comes to Emblems is that there is no way to know how to get a particular Emblem, without looking it up on the Internet, which is almost sourced from the Halo 5 Prima Guide, whose list is a perfect example of why I hate Prima: Proofreaders are apparently tok expensive to hire. The list, while mostly accurate, suffers primarily from formatting inconsistenties (such as listing an Emblem’s specifc Commendation and others as “Commendation Reward Pack”, while others are listed as “REQ Pack,” “SR [number] pack,” or simply just “Emblem”), as well as actual errors and omissions, though I can attribute some of these to pre-launch changes made after the book was written.
So far, I’ve been attempting to make a completely accurate list, updated with Emblems introduced in each update, but not knowing which Emblem comes from which Commendation has been the biggest problem. On a related note, several Rare Emblems only appear in Gold Packs. This is probably a glitch, but annoying because it means that eventually you’ll open what turns out to be a +3000 RP Silver Pack when you still have non-Commendation Rare Emblems left.
All that needs to happen to fix this problem is to add the Unlock Requirements to the description of each Emblem in the REQ Collection. There isn’t anything there besides “[emblem name] unlocked!”, and it isn’t too terribly difficult to add text of maybe a few words to ~250 Emblems. You don’t even need to write anything for those that come from normal REQ Packs, and I can send you my nearly completed list so you don’t have to figure them out yourselves.
