I'm totally ok that players can respec origin characters so that they gain more freedom choosing their companions. But narratively speaking, the level 1 classes of the origin characters should be remained as what they are. For example, I just can't imagine shadowheart talking about her goddess all the time while she is a wizard. This would definitely make her scenes very strange.
I know not all players care about this, but respec level 1 should at least be an option which players could choose to enable or not.
