Morrigan wasn't even in DA2. Flemeth is a much better link between the Warden and Hawke. And the Inquisitor, come to think of it. And even coming at it from an 'only party npc's count' thought process sti🍨ll doesn't work because, again, not in DA2. Anders would be more appropriate for connecting those two, if that was the criteria.

And I like Morrigan. But she's inching up to being over-played/hyped. Flemet𒁏h isn't, imo, because they keep her appearances brief and to the point. (My op, and YMMV obvs.)
