At the risk of repeating myself, proc based jobs used to be 1) more numerous in job ratio and 2) used to have actually a lot more rng involved.
- AST just lost all remaining rng this expansion, but even then the HW/SB version was a lot more rng based with actual control than the washed out everybody gets the same card we had in ShB/EW (with little to no control/agency over it to boot).
- BRD lost all dot proc rng in favor of a streamlined tick based repertoire system, and got "cheats" baked behind Barrage to ensure RA procs.
- DNC didn't lose rng per se but lost rng in terms of ratio to abilities, since everything new they get not only is static (DotD, Starfall, Last Step, etc) but also moved a lot of rng out of the burst window which has become a lot more static as a result with little to no triage left. Compare this to ShB burst that not only had to account for proc overwriting, but also melee range considerations...
- MCH lost all rng, where it was in reality one of the most rng DPS jobs of all in its GCD structure (with ammo agency).
- RDM is the only job that kept some manner of rng (a budget old mch ammo at home), but like DNC gets more and more fixed nukes introduced into it.
- BLM lost rng over time, which was extremely rng based in ARR, then a lot less in HW due to F4 replacing F1 spamm, and less and less in the expansions after by getting more and more control tools like sharpcast and paradox to generate those procs and guarantee them. Agency over rng is good and warranted, but not when it removes the little rng a job has left.
- MNK I guess stayed the same for the barebones ogcd rng, which I appreciate.
In short if you're a healer and loved rng, you're screwed. If you're a dps and love rng, all your options have been trimmed and you'll probably be told to just "go play BRD or DNC" even though it's shallow as it is.
