Meanwhile, in
Heart of the Swarm, the use of Raynor is mostly to get Kerrigan in a rage-fueled quest for vengeance against Mengsk, and that's actually the driving force for most of the plot. Honestly the romance elements feel pretty awful, because they're superfluous: this is the story that should have happened after
StarCraft: the Overmind is dead, the Swarms are in disarray, and a newly freed Kerrigan must rebuild the Swarm to take her revenge against Mengsk for betraying her. My perpetual frustration with
Heart of the Swarm was that it was a story that was two games late. So while I agree that the romance was awful in that game, it doesn't feel like it's the driving force of the plot. Honestly, they should probably have Raynor actually get killed and not try to make Kerrigan heroic, and again, this would probably have been great with me.
So you see, while both stories had their problems, I think
Wings of Liberty turned out pretty good nonetheless, and can see
Heart of the Swarm also being good if any of a few things had been different. But I can't see any way I would be interested in
Legacy of the Void. After
Heart of the Swarm, I was angry because they screwed up. After
Legacy of the Void, I'm sad because I have no interest in heading in the direction they're going.
