But is that really true now in the story?
The Covenant’s have assaulted major positions in the Maw. Multiple Maw Walkers have been running in and out grabbing souls.
Once converted into an armor in the Maw, going by what happened to Arthas, there’s nothing to save after.
Are we really supposed to think that the Covenant’s left masses of viable souls in the Maw, for a completely unknown future in which Sylvanas would be sent to save them?
They (Devs) might do that, but it seems a bit of a reach…
