As someone who has all 3 ranged maxed ...
I have to say, current Mch is the most braindead job in the game.
I use to think Dnc was the braindead easiest until played more DPS jobs and I noticed that not everyone plays like me. I'm a recovering clicker who mained tanks until this expac, I'm use to just looking at my hotbar for most of the fight. Dnc's RNG actually requires you pay attention to different procs, it's got a lite "rotation" based around RNG, much of what you do is priority based decision making in nature. Brd also requires you pay attention to DoTs and RNG procs and buff timers so that you can snap shot dots for more DPS.
I think the divide here is thinking that pressing a 1-2-3 over and over inherently requires more thought than actually engaging in a RNG system that demands a certain amount of your attention.
I didn't play any other version of Mch but as it is, at lvl 80 it requires the least amount of thought of any DPS imo based on what the job ask of the player. No Procs to think about, full freedom of movement, no dots or self/ party buffs to think about ontop of a rigid rotation.
It's cool if people enjoy it though, I'd never say people shouldn't like XYZ job. But personally I feel Dnc is in a GREAT spot design wise/ Brd isn't the best but not a hard thing to fix/ Mch needs more things to do and think about ... and less reliance on spamy BS as a cover up for it's design shortcomings.
