I regret not sending her on a suicide mission back in Legion.
Her presence in the story is a genuine headscratcher for me though. On one hand she’s portrayed as someone who symphatizes deeply with her former people and has demonstrated a willingness to lead them on the basis of her birthright as heir to the throne of Lordaeron.
Problem of course is that those people she seeks to lead are now part of the Horde and as such enemies of the Alliance, a faction she does have friends and connections in. There is also the small issue of there not being any rebel Forsaken for her to actually recruit for a proposed splinter faction of Alliance aligned Forsaken since Sylvanas already had them killed in BTS.
The Forsaken really are the odd ones out in this faction war U-turn we’re now seeing. Blizzard seem intent on making racial leaders the vehicles that drive this story forward and as of 8.2 every Horde race save for the Forsaken has a top tier representative who’s gone all chummy with an Alliance counterpart. Saurfang/Thrall, Bob and Baine being the main culprits with Gazlowe making a passing comment in Mechagon on the usefulness of interfactional partnerships.
Calia, for all the horrors that she represents would at least give the Forsaken a high tier character who could bring those odd ones in line with the remaining races in the Horde without being a kill on sight target for the Alliance.
But it would also severely harm the Forsaken fantasy that fans have grown to love over the years.
So I say once again: I regret not sending her on a suicide mission back in Legion.
