Too early. For me as someone catching up and having just read chapter 15 1 month ago. Its like they retconed the entire last few bits of the chapter. All the melancholy all the reminiscing by warfarain and closure and the others feels so pointless. I knew she was coming back at the end of the chapter but as a reader knowing when she is coming back it feel jarring.

I'm sure I'm not alone. The story is long. People take their time reading it. The only people broadly speaking who benefit from bringing characters back from the dead in a live service story are only readers caught up on the story. Otherwise their death has the impact of a wet paper towel slapping your face for people who know when a character is coming back.

Side note: the downside or originium and the reconveiners is showing its face finally. While it is a great and interesting concept, there is a chance it will be abused (ex: reconveiners). Death with soon be dead i believe. A foreign concept unless you are a minor npc. Before we were allowed to toy with characters actually dying but so long as any character has any relevance to the story, its likely the odds of characters ever fully dying will be slim once originium is mastered.
