Green and below can decode to anything at all.

Ah hah. Ok then. That does seem to make part of the item tag out to be rather deceptive then as it says something like "chance for rare or better", but nothing at all about it potentially being lesser as well.

While I'm thinking about it, is there a solid wiki up and running ala Halopedian? Something that could answer this type of question in lieu of the manual that's missing. Last time I looked it seemed like I found two or three, but none that seemed very comprehensive.

That said, my understanding was that engrams were (now) supposed to decode to their rarity or better all the time (green = green or better, blue = blue or better, etc). However, last night I noticed I've been getting green engrams that occasionally decode into white items.

So wtf? Is this a thing that exists in the trial but not in retail? Do I not understand how engrams are supposed to work? Has the world gone mad?

I mean, I'm not feeling gipped or anything (it's only green to white, and has almost always been for something I didn't need anyway), but it is a thing that's kind of perplexing and annoying as there's zero explanation and indication of what's going on, and what outcome I should expect (which I guess in general has kind of been par for the course since Alpha and Beta for literally just about every system in the game).

Help?
