My long-standing gripes with MCH and physical ranged in general

[CKNovel]

I don't feel like Machinist needs any more damage buffs at the moment. Take a look at the Savage statistics for the last couple of weeks at the 95% percentile, there's barely any difference between the physical ranged now. Certainly not enough to blacklist the class.

But certainly not enough to make the MCH valuable.
MCH identity is to be "pure DPS" but as said before, it doesn't do much more DPS than the other ranged and falls behind against multiple targets.
And again, it's a gauge based job, multiple donwtime only hurts the MCH. It used to be its strength when you could sit on resources for a big burst next phase but there's simply too much downtime to generate resources. And when there is a lot of uptime? It's multiple targets Ricochet and Bio Blaster can't reach. I'm not sure about Chain saw.

It's like trying a car for 10.000 that only go slightly faster than the others, except the other have utility such as GPS.

It has nothing to do with familiarity or "reputation". Even after the prog is done, HC players still believes that MCH is just the worst choice.
MCH simply lacks value over the two other ranges and its weaknesses reveal themselves in DSR. It's that simple.
