Issues with Machinist design

[Fannah]

Heat Gauge:
1. Why there is no connection between main combo and Heat Gauge? Even if Heat Gauge is at 0, we are able to use Heated Actions. It's even funnier between 54 and 64 because only some actions are Heated. Absolutely no sense.

Certainly because it was the case before and people complained MCH was too complicated, and MCH was not popular. Whatever can be said, they made MCH more popular in the end.

2. Heated Actions have way too wild animations. It's really silly that everything we do are sideflips, 360 noscope spins, or 720 backflips. And where are the bullets and gunshots? There is no gun in a gun wielding job. I know that Bard can get a little jumpy when you are blessed with good RNG, but basic actions have pretty normal animations.

Doesn't affect the gameplay, and it's all about personnal taste, some people will think it's too much, some will think it's really cool and change from more traditional moves other jobs can have.

3. Why Crossbow is related to Hypercharge? Technically it can be explained that Multitool is powered by heat, but its not, only Crossbow needs Hypercharge, everything else has its own cooldown. No sense here.
And while we are at Hypercharge - Flamethrower is not related to it at all. And we magically release flames from our gun, even though we have Multitool.

Talking about gameplay or logic ? We could also ask how the machinist lost magically the ability to do a "Grenado Shot" for Stormblood extension. "Heat Blast" also is related to Hypercharge. I wish Spread Shot could become Autocrossbow during Hypercharge.
We have the battery box to explain whatever magic we can use like Flamethrower. It uses ethereal energy, like everything in this FF world.

Battery Gauge:
4. I know it can be explained by gameplay mechanics that main combo and Hot Shot charge Battery Gauge, but i feel like it was slapped to just add something to the job and it can be simply replaced by cooldown on Automaton.
And i also feel like Turret should stay as separate summon, because it appears on all artworks (also Job Guide artwork) and even Deep Dungeon icon. It would add more variety to Machine part of the job.

I believe you're wrong on this one, it could not be a cooldown while keeping the same advantage, because the purpose is to adjust your use of it with your team buffs (whatever it's with 50 to 100 power). Everything was made to be easy : No more random cooldown, no more Heat to manage and no more Ammunitions to manage anymore, no more complicated combo with Rapid Fire Hypercharge Wildfire, no more cast time (from HW), no more need to be perfect like a 1min clock. It's even not as punishing as it used to be (but still is) to not manage your Skill Speed stat. Now you can just stack Heat and Battery and use them only when your allies use their dmg buffs to automatically use them at the right moment.
