@platy and I were just discussing this observation as well not too long ago.
Albeit a known issue within the GazettE fandom, Aoi's lack of fulfillment in the band when it comes to contributions musically or simply pitching ideas have really shown this time around. Our M&G, while amazing (I accidentally didn't attend the last M&G in 2016) it was to meet them, you could tell who was showing face for the fans, and for me it was Aoi.
This discussion could go on for hours but to keep it short, there has to be room for expression and creativity for all the members, otherwise we may see things turn DEG style where the members don't even sit in the same room at times. They've more than earned the right to breathe easy after so long, so why not actually go back to basics and let creativity fly? NINTH is a great example of this and I hope they continue in this direction in the future.
Getting back to the live itself, I also mentioned this to @platy but was the soundcheck somewhat shit for anyone else? Don't mean to sound like an ass but I noticed that Reita's bass was a tad overwhelming for the NYC stage, so the guitars sat far too back, sound-wise, for my tastes. Ruki's vocals were also slightly muddled but clear enough where no one cared. I think Kai's drums were the only somewhat "tuned to spec" instrument there. Keep in mind Kai doesn't have to switch guitars or anything but this poor soundcheck was not corrected until the encore. That's when the concert became waaaaaay more tolerable for me, and only because the techs came out to prove my suspicions and tweak things.
