I am not so sure that I could. It used to have short casts which could be bypassed by reacting to the random procs of its combo, or forcing them with ammo, granting extra mobility. It then had a system of a 30s, 60s, 90s, 120s, and 180s skills that came in and out of alignment, giving you a variety of different bursts of damage over a fight.

In Stormblood, casts were removed, simplifying proc usage as it was no longer used for mobility. The burst rotation was also streamlined by changing everything to 60s, meaning you repeat the same thing more often. In their place, they added heat, which required just as much attention as what they removed. Then they promptly turned heat into effectively one more 60s buff because people complained it was either too difficult or not rewarding enough.

The leveling experience is frankly awful, as the job doesn't feel complete until level 66. The level 70 skill, Flamethrower, is also a clunky and somewhat counterintuitive. If you stick with it to 70, you'll get a job with a very strict and static rotation that is very active and requires very strict timing for periodic bursts, but then can basically ignore it's core mechanic for 40-50 seconds until it's time to do another one. Whether you find that appealing or not is up to you.
