Honestly, I'm not sure at this point what Ishikawa's role on the team is going to be at this point. At first it seemed from her off-hand comments that she'd be stepping down, and now it looks more like she's staying on the team, though we don't know in what capacity? At the very least, she does have a lot of influence, and - IIRC - has mentioned she's going to be working on the stuff that continues to "clarify" and handle aspects of EW's story. I can understand your concerns, though. (Personally, I like Maehiro's work, but Heavensward, while solid and admirable, didn't personally engage me nearly as hard as Shadowbringers or the parts I enjoyed of Endwalker.)
As for Hermes, I completely disagree with that reading of Hermes's actions, but it didn't really make me angry, either, as I sort of took the way he was positioned in this quest in particular as having some meta element in it: first off, pointing out that if we're praising Venat, it follows that we must praise Hermes as well, and also, Omega was basically acting as contrarian to the general fandom (and MSQ narrative at large) - the reception/treatment of Emet/Venat skews positive, so it points out the harmful aspects of their actions, and it's the opposite of Hermes.How did you feel about the positing of Hermes and the Final Days being some kind of net positive for the world?
Trying to wrangle something positive out of Hermes's actions re: the Final Days is an extreme stretch for me, to put it mildly, but I can tolerate this sort of thing as long as it's not being forced upon me and is treated more like a thought exercise. It is true that Hermes's actions played a key role in shaping the events leading to the present we play the game in, just like the Sundering and the Rejoinings.
Once again, though, I understand people who find the continued sympathy extended towards Hermes - and asking us to give him certain forms of benefits of the doubt that aren't well-supported by the text - extremely frustrating.
