Alani and the other characters, as well as the maps and modes would all be better categorized as additional content.
It’s all stuffed planned to be in the game that didn’t make it in for launch.
It’s included in the purchase.
The paid campaign missions more fit the implication people use with the term dlc, as it typically describes content paid for after the fact.
So why would the dlc focus on the additional content characters when the dlc is still being kneaded(not even in the oven yet)?
Besides we know the dlc focuses on the fight against the varelsi as its simply a continuation of the existing campaign.
It might be interesting if they did connect one of the later characters, namely the one that might be lenore, because that would be nice. You know, having a narrative.
But I feel there is honestly no reason at all to think one has any influence on the other. The timeframe just isn’t correct
