The Origin stories will obviously be revealed on your first playthrough because they are also companions. Why would you replay as any of them?
Your own PC you can replay because it's a brand new character every time. Origin characters will just be more of the same.
I just think the whole Origin concept is a huge waste of resources. And it sucks because we already know too much about them as companions before even meeting them. Their background and secrets are just blurted out in char gen description.
I totally agree with this. Unlike many here I don't find them a waste of resources, as I look forward to have them as companions. It doesn't matter they're not optimized because the game is easy enough for them to dealw ith it anyway. I find all of them itneresting in their own way and really look forward to see how their story archs play out, but there is no need to play them myself as I sort of do anyway when I control them as companions.
So instead I'll make a list of the most interesting ones.
1. Karlach (pretty sure she'll be a companion) 2. Shadowheart 3. Astarion 4. Wyll 5. Lae'zel 6. Gale
