The same Problems were also stated about Ninja and too a extent monk also, OGCDs and faster rotations have always impacted higher Ping Rotations, and your changes would Not work.
1) your fix doesnt fix the DPS Difference between a Low and high Ping.
2) It doesnt deal with Double Weaving which is another thing that impacts people of a high Ping.
Due to how FFXIV Combat works, Fast rotations Dont Work on high Ping at all, because the only way to ramp Speed into Rotations is Simply by OGCDs Faster GCDs and Double Weaving. which all impact a player with high ping, so while no the term "latency problem" isnt a playstyle, the Playstyle Adopted CAUSES "latency problems" and cant be Performed without those flaws existing.
the only way to make FFXIV Entirely high ping friendly, is to all together slow down combat even further and Reduce the Options for players who want fast rotations.
they did CREATE a high ping friendly Machinist,
its Called Bard. i highly Suspect, they also Partly changed Bard into a DPS so they could have a high ping alternative to Machinist as Bard has been created with ALOT less OGCDs and no Reduced GCDs, thus giving players as yourself a Option to be a Pure Ranged Physical DPS Also without taking the possibility of a Fast rotation away from those who want it. this is also another thing i've not understood about these arguments, Most say "we dont need Spammy Low Damage attacks, Combining the damage would perform the same DPS on Slower Rotations" but Bard is exactly that, its a high DPS roughly the same point as Machinist DPS wise. and offers Slower bigger Hits with its abilities, with what can be compared to Just Nukes. yet you all Reject Bard. So clearly, you want the Spammy low damage attacks. because ur prefering it to Bard which is Exactly what your asking for.
Condensing Machinist down will litterally make us a bard Copy, Bards do the same thing as Machinists almost, the differences Lies alot of its Damage comes from its DoTs and Heavy hitting attacks, but its OGCD options are far smaller, with no Weaving, no double weaving, and no bursts of Low GCD moments or Spamming. so if ur Ideal Machinist are these changes, bard should effectively be perfect for you....
Machinist has been Unfriendly to high ping for over 2 years now, Realistically they havent taken anything away from you. to make Machinist high ping friendly and get a high ping player on the same DPS as a Low Ping Player, the Job would have to lose Double weaving capability, Lower GCD Capability, and the quantity of Spam Abilities it has. it'd require a Second overhaul to make work, or they'd just half fix it and leave us in the same state as we were for the entirity of SB.
whats the point in introducing changes. if It still doesnt fix the job for high ping players and to that end, is Removing Fast paced OGCD heavy Playstyles from the game entirely Worth it. Because it will lose them players, theres no reason Something like Machinist cant exist providing theres Alternatives to machinist.
not every job in the game has to be catered to every player in the game, Jobs are options, 90% of the Jobs run on slower Rotations and are made in a way to be high ping friendly, theres nothing wrong with those who do have Low Ping to pull off the Accelerated Gameplay wanting a Choice also.
your fix also causes multiple other problems. if ur able to Pre-use it to Generate 5 charges, it could become Meta to cast it before a fight by so many Seconds to Then get off a Second burst sooner, which could lead into More problems. The last thing we want is to be Another Job that gets wrecked everytime someone immediately pulls the boss. it doesnt fix the problems at all, your problem garuntees a final heatblast.. but your still not going to perform like a Low Ping player, u have no access to the Machinist Double Weaving capability. your still gonbig to be the exact same behind a Low Ping player, ur fixs just make it sound better on paper, but in reality wouldnt change a Dime. if the the fixs were that easy SE would have Implemented them.
the reason these QoLs Dont exist, because they dont work, FFXIV Combat is set up in a Way Ping Affects it, Thats a Inherit flaw of the Systems in itself, but nothing can be perfect. for high ping and low ping players to perform at the same Level, u would have to remove OGCDs, Weaving, Abilities that lower GCDs and Timers all together, because there are people over 400 MS Playing this game, if they're going to cater to u at 200MS why shouldnt they then cater to 400MS.. why not ascend to a point where we have 6 buttons we press in a row continously. to ensure no ones at a disadvantage, while at that Why not Reduce the games Graphical Ability to cater to those with worse PCs.
the list of QoLs to cater to players Problems is ENDLESS, if u start fixing them this will pass to the next problematic Topics, no game provides a World where NO ONES at a advantage. that is why MMORPGS fix the problem by introducing Different Jobs. so if one DOesnt work the Next will, Jobs are not built to cater to everyone, they're built to give People a Option.
its defintly 5, i have 26 Ping, and cannot do 6, the animation doesnt work at all even if u try to cast a 6 while the buttons Still glowing, so it should be pretty doable aslong as ur Ping isnt completely wrecked.
