So, can anyone tell me why all of my Dragon Age: Origins Wardens and all my DA2 Hawke aren't in the Keep? I'd really like to use some of them that are not there. Also, can I delete any of them? I don't mean the world, I mean from the options/the card-like things.
The easy one first: no, you can't delete the tiles. It has been suggested (several times!) because some people have the same Hero showing up more than once (for example, if they have separate saves for DA:O, DAO:A, Witch Hunt etc.). In the run up to the launch date, however, I guess there were just bigger and more pressing priorities.
The more difficult one: there seem to be many, many possible reasons why your heroes might not be showing up in the Keep (so-called "syncing"). It can depend, for example, on the browser you're using, the platform you're playing on,whether your Origin account is correctly linked up, or whether you've changed your PC settings. Go to the DA Keep forum, and there's a full FAQ covering the possible reasons and potential solutions. One of those might work, but there are still a lot of people (me included!) for whom syncing is still not working and who have one, some or all of their heroes still missing, even after trying everything in the FAQs.
On the plus side, we're assured the lack of our heroes in the Keep won't affect DA:I because the Warden doesn't appear and Hawke, who does, is customisable in-game. I can't confirm if that's true because the game isn't released here in dear ol' Blighty until Friday, but that's what we've been told.
