All, in order:
- SAM - It's just straight-up really well crafted, with no particular warts or similar weirdness outside of Kaiten arguably being bloat and Kenki being a bit weird before 64, not that such is a particularly long span for a 50+ job.
- BLM - Though the pre- vs. post-74 disparity (and the rapidly obsolete skills in general) are an oddly large annoyance, this is still a really great job; if not for its outright effectively removing mechanics through traits instead of polishing their original forms, this would beat out SAM.
- DRG - Just distract yourself from noticing the skill bloat of 7-button rigid 10-step ST combos and you're golden; DRG has plenty of macrorotational depth in the forms of resource banking and Lance Charge alignments.
- SMN - It lot of the good stuff seen from DRG, but with more clunkiness; though I've placed it here, I'd still often take it over DRG for the added flexibility and utility of being a caster.
- BRD - Not much to say here; it has its disappointments and issues, but it's at least a complete and decently deep job, in context.
- NIN - This one's still fun, but a shadow of what it was in 5.0; if only it could have simply gotten the TCJ change, allowed mudras to queue correctly, and been tuned correctly... without the rotational gutting or reduced fluidity for low-ping players... For those who don't know what they're missing, it might go up a place or three.
- RDM - A job that's decently "complete" but only from and around mechanics that add more fluff than depth; it can also be a turn-off that its sword is almost solely an added liability rather than an advantage.
- MNK - 4.3 Monk was god-like, imo. Current MNK is instead somehow less entertaining, even, than ARR Monk. It's basic, plays tight when approaching anything near optimal play, and is still rife with bloat. Also known as "Leaden Fist and remaining RoE/TN charges vs. spin-Tank and/or forced-facing mechanics."
- DNC / MCH - The first is an ultimately very simple bank-and-burn RNG fest and the second is as shallow as it gets. I suppose they're good if you really like enjoy the life of the casual proc-watcher or ceaselessly cycling 1-2-3 between 20, 40, and 60-second CDs.
