I'm just giving credit where it's due. I did talk to mentors and they helped me understand the peculiarities of each job, which led me to this alignment instead of the one from three months ago. They made guides and simulators which I looked over to get an understanding of each classes rotation to a certain extent. That said, they did not have a direct hand in making this list or endorsing it, and I stated as such in the disclaimer (which, not surprisingly, most people gloss over).
I just curious as to why people believe these are terribly subpar, especially in a situation that gives you the same number of casts whether you use raid buffs as soon as possible or delay them a bit. Here's what each class is using in this alignment, at 15 secs:
NIN: It's whole TA window, which contains most of it's strongest GCDs (1 Hyosho Ranryu, 2 Raitons, 1 Fuma-Raiton-Suiton TCJ, and ShadowFang) and almost all it's oGCDs (2 hits of Bunshin, DwD, Assassinate, and one Bhava (possibly two depending on how late TA is used).
DRG: Everything from a LS Full Thrust to the second Chaos Thrust. (It still retains the use of all the oGCDs even in the early raid buff opener).
MNK:
-Anatman Opener: If Anatman opener is delayed by 1 GCD (unfortunately), then everything from the 1 Boot to the second Demo falls under raid buffs.
-TK opener: The 15 sec raid buffs should hit everything from the first Boot to the last True, with Litany and Voice possibly reaching TK RoF is used around the same time as those buffs.
SAM: It fits Midare, Tsubame (basically the second Midare), Higanbana, Senei, and Shoha within 15 sec raid buffs whether they come out at 10 or 15secs.
DNC: The second Standard Step, Saber Dance procs, and a majority of Flourish moves all fit within raid buffs (though the more SDs you get, the more procs get pushed out, though since the only way to exceed SD's damage is to use FF/BS+FD1+FD3, the latter two being proc based, I don't see the problem with this so long as you don't lose a Flourish proc).
BRD: Pushes back the refresh of IJ, so more dot ticks from the first two Dots (can't say anything on the WM timings since that's proc based).
MCH: Fits hypercharge window, Drill, and HCS, as well as 6 (possibly seven) casts of both GR and Ricochet.
BLM: Fits 2 F4s, 2 Despairs, and 1 Thundercloud with Litany and Voice possibly reaching Xeno.
SMN: Fits all for R4s, 2 Festers, 2 Enkindle Baha, and 6 WWs (possibly the DeathFlare, but not sure on that one).
RDM: The entire melee combo, CaC, Displace, VerFlare, Scorch, Verfire, VerAero, Fleche, and possibly Jolt 2 (possibly Verstone if it procs). 8th GCD Embolden also provides a bigger boost to the melee combo, VerFlare, and Scorch, all of which are also buffed by Manafication.
PLD:
-FoF opener: Fits in 2 Atones, 2 Intervenes, a Goring combo, CoS, Requiescat, and 1 HS.
-Req opener: Fits Confeti, a gore combo, an extra FB and RB, 2 intervenes, and CoS.
WAR: Fits 2 ICs and 5 FCs under IR, as well as Onslaught and Upheave.
DRK: Fits nearly all of the LS's attacks, 5 Bloodspillers, 4 EoS without MP overcapping, AD, Salted, and Plunge (if you double weave it at least.)
GNB: Their entire Gnashing combo, as well as Sonic Break, at least 2 Burst strikes, 2 plunges, and an extra BZ.
WHM: The use of PoM allows for 3 Glares, plus a Dia, which is refreshed later while still managing to catch raid buffs.
AST: Isn't as frantic to play 3 cards before Div, doesn't waste a GCD of Lightspeed, and delays the refresh of Combust while still catching raid buffs.
SCH: Fits 4 Energy drains and refreshes Bio later with both casts catching the Pot window.
Admittedly, there are probably discrepancies in the timings, but this is the general goal. So again, if the number of casts is the same regardless of using buffs early or not, what makes the goal of a delayed alignment so subpar?
