Regarding the baseless idea that /NIN takes long to get hate compared to /WAR is getting old... I'll go over it slowly with details for Jamal.
Hate tools for PLD main include:
Flash (1280VE, 180CE),
Sentinel (1800VE, 1CE, Enmity+100 for the duration; equivalently enmity+100%),
Shield Bash (900VE, 1CE),
Cures (CE = 0.7275 x HP Cured, VE = 4.4 x HP Cured),
Rampart (300VE/person).
/WAR gives:
Provoke (1800 VE, 1CE), Warcry (300VE/person) and lolDefender (80VE)
/NIN gives:
Incredible survivability through Utsusemi, saves babies by day, cures cancer by night, feeds Africa, etc.
VE caps at 10,000VE, CE caps at 10,000CE. VE decays at 60VE/sec, CE is lost by taking damage or shadows (-25CE)
If a PLD/NIN did Sentinel > Flash/Shield Bash/Cure IV @390HP that would generate...
1800VE + 1280VE x2 + 900VE x2 + 4.4 x 390HP x 2 = ...
9,592VE (The cap is 10,000VE, rendering Provoke utterly and completely useless for 99% of HNM, sea jailers, sky gods, Nyzul Bosses and MORE!)
Yes, I had to make it super big for super emphasis and super truth.
Sky gods - Just because you can make /WAR "work' doesn't mean it's optimal, MP efficient and good hate. I've dual tanked sky gods as WAR/NIN with TAs for hate just as you have with PLD/WAR, so why don't we all just use WAR/NIN now because it works too!
Limbus (barring u/o) - Again, making something work doesn't mean it's optimal, etc. When you say /WAR is better, are you assuming you have a dumb number of people for Limbus? Over 2 parties for any zone is dumb, roughly 4-8 people is safe and even excessive for many zones (Apollyon NW for example). You can't do that with /WAR.
HNM (except KB) - You can hold Tiamat, Vrtra, Cerberus, Khimaira, Nidhogg and everything short of AV forever with PLD/NINx2, BRDx2, WHM and RDM. Replace that with PLD/WAR and does not compute. If you wanted PLD/WAR to work here, you need more support (I thought /NIN needs more support?). When we've had few people on and Adamantoise is up and unclaimed (with other linkshells rushing there), we've had PLD/NIN hold solo for incredibly long, I can't imagine PLD/WAR doing the same. And again, because you can make it work is not a valid point. Nny on my old server tanked Fafnir as WAR/MNK. Did it work? Yes. Was it effective, optimal, useful, etc not really. And how could you say NIN is better for Tiamat than PLD?
Nyzul - Yes, I was referring to the boss floors since you can't prepare for any other floors.
Meriting - Depending on party setup (having a BRD and RDM), /NIN is possible 60+. PLD/NIN meriting isn't as bad as you claim, it's as good as a WAR without the brains to use Great Axe.
