A. Gwynn wasn't re-spawned by the nexus.

B. We would have a thing to do. Namely, assault the Blood Countess Victoire's castle, and attempt to claw our way out of hell. And if the Blood Countess doesn't defend it to participate in the battle, we probably get Diana/Bastion back. If the Blood Countess does defend it, we're helping out the battle by depriving the demonic forces of one of their strongest.

C. Those three characters that were killed and not respawned were high level, strong charismatic angels, commanders each worth more than the entire forces they lead. The fact that the nexus didn't respawn any of them is a harsh blow, especially seeing that the angels are literally reduced to leading their forces with a ghost and a zombie (albeit really awesome ones. Good job guys). While, yeah, the war isn't over for the angels, someone who was already cynical about the Angel's chances of winning (Miyu) might believe it to be.
