After having spent some time watching the fights and doing them myself, I feel that I'd comment on the decision by the raid team in terms of the difficulty, as well as the decision to give us an extra week.
First of all, the general balance of the first 3 fights was top notch. I also appreciate giving us extra time to enjoy the story and prepare for the raid as it was one of the more 'restful' raiding progressions I've had so I was able to enjoy it without being overly stressed out.
That said however, Yoshida specifically mentioned the fight tuning was not inclusive of the extra week, the extreme weapon or crafted gear and I feel this was a little disingenuous.
The door boss for P8S 100% factored in the use of a tome weapon upgrade being allocated to one of the DPS in the party which wouldn't have been possible without 500 tomes in order to beat the check consistently. This is coming from my Free Company which has cleared this tier week 1 in all the other previous savages.
Group composition is BLM/NIN/RDM/DNC/PLD/GNB/SGE/WHM if people were curious.
Content like this should be enjoyable and the fact that said group was incapable of bypassing the door boss, let alone progressing through the second phase is truly a shame and it truly demoralizes the raiders that because of composition of the team and gearing that they weren't able to defeat it.
While I appreciate the desire to challenge raiders, something like this shouldn't force other players to either switch their jobs or at the very least, need to procure a tomestone weapon on the first week of raid without forewarning that it is required. (Many of us spent tomes on the pants, rather than the weapon expecting it would be a sufficient upgrade.)
I do enjoy the world race, and the challenge but I would ask that in the future that information be more clear to allow more players to enjoy the content and the challenge especially stating that the difference of a weapon would have allowed us to likely beat the check instead of repeatedly wiped on 50.2% even without any errors on the player's parts.
Regardless, this is a very fun design both from the mechanics, and gameplay and I look forward to future raiding content. Just be a little kinder to those of us who aren't focused so heavily on meta jobs and the necessity to play specific ones to meet certain difficulty checks.
