The only reason I suggest making it rotate with Scatter Gun is because Square seems to be very inclined into giving the jobs the least ammount of buttons possible...
Otherwise I'd not only suggest Bioblaster be his own button, but also Hypercharge that then changes to Heat Blast, charged with Heat stacks that DOESN'T DECAY, so you can actually have some degree of control over your Overheat window.
But if they're gonna go with the least ammount of buttons, Bioblaster actually does have the same range of Scatter Gun so using one after the other doesn't seem that bad. If anything you'd need to cleanse Scatter Gun to be able to get Bioblaster. (You'd also need to just assume he has his primed effect by default since Analyze is designed to work with the other button.)
Exactly my point. And I hate it with a burning passion.
Nah, I don't think it is incompetence in this case. I think the Idea is making sure that this guy is forced into a range where the other players can kill him. That's why so many ranged classes have close-ranged cones/dashes. Which in one way I get, you don't want people just permanently in the safety of their 25y just kiting players.
It's just that Machinist is uniquely disabled in the name of that. He already has Scatter Gun which would slot in the same place as SCH's Mumify, BLM's Burst, SMN's Crimson Cyclone, BRD's Repelling Shot, WHM's Seraph Strke... But he ADDITIONALLY has to deal with that on Bioblaster, on top of already essentially never being able to Scatter Gun because you need to think about dumping Bioblaster first (And you can't even weave Scatter Gun like you used to be able to Blank.)
They want to make ranged people close into melee people so they're not constantly kiting (Like happened a lot before 6.1), but they DOUBLED DOWN on Machinist. And when Machinist finally found something good about that lock, they made sure it didn't work. To make damn certain that Bioblaster is a PUNISHMENT, not an actual tool.
