I do agree that being forced to stand still completely for current Flamethrower doesn't help the current situation, hence I have put in that it should also allow you to walk with it much like Blast Charge currently does, although I can't ignore that with how Heat buildup was as early as Shadowbringers, the damage is still lackluster since at most you only want to use Flamethrower for 2 seconds anyway before just building up Heat since Heat is far more powerful. Currently, I do prefer the idea of having the 2.5 GCD timer only to "cast" it(while still letting you walk around), but then it comes out instantly without having to hold it down and it gives you a buff to make using the rest of your skills even more damaging. This would also put it on a similar level to be thrown in with Drill/AA/Chain Saw/Marksman's Spite(name pending), but it would essentially be the first skill to use in order to inflict large damage instantly but also buff your opener and your resulting combination of Drill/AA/Chain Saw/Marksman's Spite.
I mainly put Dismantle at 5% to not step on too many toes but also to make it too overpowered for a short cooldown, I would not be opposed to 10% however. I just desire to have better role actions, as currently Physical Ranged(which I was considering as a whole with that section, not just Machinist) has the fewest Role Actions in terms of usability, as Foot/Leg Graze are far too situational even among niche content like POTD and such to be considered usable. Stun is difficult to put in given its near uselessness when bossing(for the most part), but also it can clash with some other kits like White Mage's Holy, and that's not considering immunities as a whole. With Hawk's Eye at least, it would serve as a strong DPS tool for all Physical Ranged to bump them up further as they do substantially less than every other job, so at least lowering the gap would be helpful. Palisade is a sorely missed skill in my opinion, and it wouldn't be too crazy to bring back in since it already existed which was primarily what I was drawing upon.
That would be cool to have Grenado Shot upgrade as it goes along. I have it considered as part of the big buttons to press like Drill and etc. I didn't think of the upgrades much admittedly simply because I didn't have any more room on Photoshopping things like that without diverging too much from what was already here.
