First of all I want to get it out of the way.
The game is not out for very long, and I've experienced only a tiny slice of what EA has to offer (6 hours currently in).
That being said said the background choice so far feels more like two free proficiences, rather than a major component of your character. Especially considering the classes are incorporated wonderfully, I love the dialogues choices you are given based on the class you have chosen. I wish the same could be said about the background, an especially prominent example I've encountered was in the tiefling/druid encampent.
In tl;dr, I wish we had more dialogue options, or at least some rolls modifiers based on the background we have chosen, rather than on the class alone.
Especially considering we do not get the background traits for understandable reasons.
