The main issue that they've written themselves into from a lore standpoint is in tying all the pre-existing worldbuilding elements back to Amaurot, in a reflexive response to the accidental popularity of a few overvalued characters. Garlemald and Allag are just puppet states created under Emet-Selch's influence. The Void was the byproduct of the usual Ascian ignorance and malice. The Twelve are the remnants of Amaurotine souls.

There's a particularly obsessive and vocal section of this community that is fixated on Amaurot and its pretty characters, but there's no way to satisfy them anyways. The best solution is to write Amaurot out of the story and start fresh worldbuilding that isn't connected at all to it. Thankfully the coming expansion seems to be the start of this.
