The DLC IS NOT CUT CONTENT nor IS THE CHARACTER REQUIRED TO GET THE FULL EXPERIANCE

I think there's a lot of misinformation out there and I wish the guy who made the initial video about it would have had an open mind before jumping to conclusions based on a leak we weren't ready to address. Since I'm a BioWare employee, I know people won't automatically trust me, but I hope people will consider that it wasn't cut content from the larger game. I was in Edmonton when we were finishing the game in November/December and I was in Edmonton again last month when they were working on the Day 1 DLC. It definitely was only possible to do because the main game was in certification (which means we had to wait for people to test it and make sure everything was good etc before we could get the greenlight to sell it). I also played the game WITHOUT the DLC in my first playthrough and honestly, it's an awesome addition but I was more than happy with what I was given in the game. It's bigger and more expansive than ever. Of course, I understand the concern but I hope we can all have an intelligent conversation about it and cover what the facts are in this situation.
Hope that helps a little bit. This is an awkward format to answer this question, but I know I could explain it if you were sitting next to me on a couch with some coffee/tea

I hope you understand that I'm in a position where to reassure you, it would require me to reveal story spoilers, something that I don't think is acceptable.
Personally, I began my career as an archaeologist (for serious!) and the events surrounding this new character speak to me. However, if it wasn't DLC, it definitely wouldn't have been in the main game. There's other things that didn't fit in the main game that may end up as future DLC.
Again, I think this is a cool edition and definitely intended as a reward for serious fans (many of whom have purchased the collector's edition so this isn't even an issue for them). However, I have played the game without it and the lore surrounding the DLC is in the game already, this character just gives their own take on it.
Was that any less vague or helpful to anyone?
