-Mass Effect Legendary Edition have all dlc included except for 1 dlc from Mass Effect 1 so no need to claim them

-Dragon Age Inquisition never needed Bioware point for dlc, they are only available if you pay with real money

So it's normal for you to only see Dragen Age Origins dlc

ME1 isn't relevant here since the DLC should already be automatically included in digital copies. They are not "claimable" in any way since that is no longer a thing, and not a part of what's going on here now.

Again, this only affects ME2 and ME3 (except multiplayer), Dragon Age: Origins and Dragon Age II, as they are the titles affected by the retirement of the Bioware credits system. That is all.

Since I only have about a dozen games on origins, I'm clicking them all, and I see a few free things for DA Inquisition. I don't know if they were already there (never looked before) or they appeared recently. What I see is:

Destruction Multiplayer Expansion
Dragonslayer Multiplayer Expansion
Black Emporium
English voiceover pack

I'll update if I see anything else.

EDIT

Sims 4
Legacy edition
Holiday pack

Thank you for info I just picked up legacy edition DLC :)

The Mass Effect DVD is second hand. Dragon Age was a gift I got new.
I also have a Mass Effect 3 DVD in the jewel case but no box or manual, but it wouldn't let me register it and play when I try to install It said the key was already used so the DVD is useless.
I got the DVD from a library "book sale", so I can't take it back to a store. It only cost a buck or two however (Usually the DVDs are $2, but one sale every year they sell them for $1 and I can't recall which sale).
Isn't DRM nice? A wonderful tool to take away the Right of First Sale.

Right of First Sale is a doctrine that puts a limitation on copyright holders from dictating who gets the right to sell said copyright holder's products. This has nothing to do with DRM and isn't applicable on your issue since that's also gonna be the same for you buying from any licensed retailer.

To download the game through Origin, you may have to just put the disc in your drive, but not run any setup programs. The Origin client should detect the disc*.

*Note: You'll get the same "code is used" message when reinstalling the game from the disc. The codes are designed to used only once, which is why you'd have to use the Origin Client to reinstall it.

Not trying to be 'that guy' but could we start a different thread to discuss this topic? It's starting to clutter this thread.

Indeed. Good that the downvote squad got phased out and it no longer stifles any sort of discussion, but this thread does have a quite clear purpose.
And there is another topic for discussing massive giveaways.
