The shelf life argument makes sense for fights like Thordan (which is more cutscene than fight at this point) or even Shinryu, considering many jobs went through significant changes and we had a big stat squish with Endwalker. But this thread started with the final 6.0 fight as example, all we got since then is better gear and minor tweaks like potency changes. This content is far from anything one would consider "dated" and a very big part for a story arch that technically started with 1.0 over 10 years ago. This fight should feel impactful for new players, it shouldn't require me to deliberately hold back with DPS just so the fight is remotely as impactful to them like it was for me during pre-order.
Apart from this: It *is* an MMORPG and as much as many people who have been with us for a while like to dismiss it, new people sign up every day and experience the MSQ for the first time. They shouldn't be punished for not being able to play this game ten years ago and on every release day/patch day since. Especially not in a game that says "everyone can play it at their own pace" and "no content is truly obsolete" as part of their unique selling point. If content being dated is making the MSQ experience disappointing in a story heavy game from a story heavy franchise, it's on the devs to do something against it. And considering they already did this with dungeons with item level sync and lately also some reworks, I really don't see why they shouldn't do this with trials either. At least for MSQ relevant trials like Thordan, Seat of Sacrifice or Endsinger. (I don't really mind not seeing all phases of the Four Lords trials or the Warring Triad, because they are not MSQ, but the more the merrier.)
