As an actual response to Kalico's main point, blu is excellent at spike damage in certain situations.
In exp, with the use of MP drainkiss and magic hammer, a very good blu can keep up or surpass a
decent [insert random DD here], but a very good [insert random DD here] will always surpass the best blu in the world.
In limbus/salvage/nyzul isle blu is an extremely good DD even ignoring the support and versatility side of the job.
Dynamis, is a bit hard for me to say because I've only just started doing it again, mod DEF and evasion is a little higher than your standard exp mob I'd say, so blu in general is going to start to fall behind a little here, but a well equipped blu should be able to keep up fairly well for the most part. The waiting in between pulls really helps in blus favour because it allows us to get some MP back and then burn a lot more than we normally would on each mob.
Sea/Sky farming, well who really cares, but blu should be able to do decently on pretty much anything aside from aerns, but for those I go /thf and tip the scales with CASA Vertical Cleave SC's.
Sea gods aside from JoL blu is really good because of the versatility more than anything else.
-Ix's; depending on how you fight them blu is situationally good, the way my LS does them my blu comes out pretty well
-Temp you have the ability to do decent numbers in slashing and piercing (blunt we stop damage and kite, but otherwise hysteric barrage, frenetic rip and cannonball are all excellent).
-Fort is good as you can go from tp burning the balls one second to doing decent magic damage on fort itself the next
-Faith just sucks monkey balls regardless of what you do, but ranged cannonballs and breath spells both work quite well, breath spells are troublesome though thanks to taking damage from aoe easily. (depends how you fight it too)
-Hope; with a good breath set-up I've been highest DD on hope several times as they go completely unresisted for max damage whereas nukes don't from what I've seen, although last time on this it required heavy cure spamming on me from our whm <_<
-Justice; blu is useless on, but can do decent crowd control on charmed people if your brd sucks
-Prudence; depending on how you do it, we let one depop and burn the other (tp and mp) so blu is decent for this, but any other job will probably out DD due to pretty sucky DEF but decent evasion.
sky gods Blu is a joke, aside from storing up tp prior to the fight and doing a solo SC for mages to MB and spamming diamondhide, blu isn't a great lot of good. Pretty ***damage on everything unless you're /thf, and doing decent damage once a minute doesn't mean much when gods die in about 15 minutes for a mediocre shell.
HNM I've never done, but would be much the same story as sky gods in many respects. SA cannonball or breath attacks would be decent for anything you're not meleeing, but both of these will be situationally non-viable or just plain ***.
Einherjar is the one point you brought up that I really wanted to comment on though. The def on mobs in here is well against blus favour, you say that blu can tank Einherjar, but wow, if you can hold hate in Einherjar on blu I don't know how the hell you'll ever win even a T1, because your real DD jobs are all doing something incredibly wrong. Blu can actually do quite well as crowd control, but blms and brds to it better. If you're blu in Einherjar I'd suggest going heavy on the support spells, full use of frightful roar and stinking gas on the biggest groups of slept mobs you can find, also sound blast if you're mage heavy. Skeletons and slimes/clots you'll be wanting to spam diamondhide as much as humanly possible (use AF body and full haste gear including turban, diamondhide caps at 200 damage so relic head is pointless with full merits). Slimes/clots you can also do some regurgitation spam for better damage/mp ratio than any of your physical spells will be doing, but probably better to save your mp for diamondhide, emergency cures and let the real DD take care of the killing. Imps are probably the one mob in all of einherjar that it's good to have a blu for, I'd reccommend having echo drops macro'd for this unless you have a really good supporter who's watching out for you (which you generally won't). Imps are the one time in all of Einherjar that you can expect to pull hate on blu.
