SkillSpeed on the Machinist Raid Weapon is a big joke.

Yesterday, I got all the stuff that aren't bis for mch (Collar, ring, boots, gloves) and so I decided to give a try by replacing the 380 crafted gloves, 390 boots, 380 crafted collar & 390 ring I had. (psa: My crafted aren't penta, outside of the bis crafted ring)

Bringing my GCD from 2.43 to 2.37, my dps was lower with four 400 items than with the other stuff I had. It's not even a "little" increase, it's just flat lower because of the horrible clipping.

That's probably how bad sks is for mch, it's not even making your dps the same, it's just an handicap that lower it.

Hello, I believe there is a way to play MCH with Sks with a 60sec rotation as we can have plenty of it now.
I just think 2.22GCD is a good GCD too (I don't talk about people with high ping, sry). Yes that needs a lot of Sks but we can easily have it now at the end of this expansion.
Basically, we, MCH, want a perfect rotation of 60sec.
Rapid Fire makes 3 GCD to be 1.5sec. So 3*1.5 = 4.5sec.
60-4.5 = 55.5sec
55.5/25 = 2.22GCD exactly --> (the 25, is the number of GCD to use during the 55.5sec without Rapid Fire. So with the 3 GCD under Rapid Fire, it makes a total of 28GCD per minute instead of 25 or 26GCD iirc.

Here is an exemple of a 2.22GCD rotation (I'm not saying it's good, I mean there may be a way with that) :

Problem is that your double weaving will clip, making it worse and lose gcd in the end, delaying everything.

Unfortunately weird substats on omega weapons are not limited to MCH's. Almost all jobs have suboptimal substats on their 405 weapons. To be honest, it looks like a deliberate choice to convince raiders to do eureka in they want the true BiS.

The problem with SkS is multifold. You can't just look at a number that will get you 60s rotation because you need your entire kit to align. That means you need a GCD speed that will get you ~60s AND fit every single oGCD usage neatly between those GCDs. Assuming static rotation length, SkS does nothing for your oGCD damage due to oGCD cooldowns. It also does nothing for your turret damage, so you end up with extremely bad dps scaling.

In every single case, the rotations calculated in the 2.43-2.50 GCD range have performed the best. Adding SkS beyond that enters a range where clipping occurs and all gains from SkS are lost. Another well aligned range starts around ~2.38 gcd and below, but not only do you have to add GCDs in the weakest parts of the rotation (lockout), at that point you have also given up so many other better scaling stats that even if the rotation aligns well again, your damage is going to be very poor. It's entirely possible that there's another good GCD range at 2.22 GCD, but SkS is so inefficient at scaling MCH dps that it's not going to be worth it.

Unfortunately, it's long been speculated they simply use an algorithm to automate the sub stats on gear. Which makes sense, in theory. There just isn't much in the way of quality control hence why we see awful combinations. Let us never forget the Alexandrian Metal Guillotine and its duo useless stats in Skill Speed and Parry.

It is more likely substats are chosen in a direct counter to standard BIS. Unfortunately, substats aren't nearly interesting enough where shaking it up does anything but frustrate people.

The itemization in this game is built around simplicity, as is everything else. That's why we get 'potency' instead of damage ranges on tooltips, that's why we don't get the exact number that Critical/Det/etc work on without having some dedicated individuals do heavy number crunching.

"Higher" is "Better" in an overwhelming majority of the game. The small portion where it isn't is about the same percent as the amount of people who push and clear Savage tiers, and it's often based around breakpoints, CD alignment, or other nuances that, even in savage, you really just don't need.
