Come now, you think people are happy with MCH purely because of its dps? Have you forgotten that even after they heavily buffed SB MCH, that still no one played it because it was so bad that the devs had to apologies for its state and promise a rework because not only was it borderline unplayable for some people, it wasn't fun either, it was an incredibly clumsy and overly punishing job I played quite a bit of SB MCH and as someone who has also played since HW, I would argue that its SB incarnation is still the worst by far, which was so bad that its poor design bled into ShB MCH and is the cause of most of its issues, using flamethrower to slip into overheat never felt good, reapplying the gauss barrel never felt good, losing GCD uptime because the heated shots reverted back to the normal ones at the wrong time never felt good, it was a disjointed, poorly cobbled together mess that wasn't even fun to level due to its pathetically poor skill spread, I will agree that HW MCH was its best incarnation, but not that ShB is its worst, you think ShB MCH is a ghastly mockery of the true job? No, that dishonor goes firmly to SB MCH, the ultimate blemish on MCHs legacy that almost killed the job due to its woeful design and peak unpopularity.
ShB MCH takes MCH in a more focused direction, it focuses on GCD optimization and speed/cooldown resets, you constantly keep an eye on your timings and try to ensure there is no overlap/overcapping when you use hypercharge, you are given some wiggle room to work with, this gives the job a strong sense of flow, you try to argue that things flow unnaturally with each other, but this is objectively untrue, everything falls into place as you play, you are always building resources to spend, resources you can either spend immediately or keep for raid buffs, this is why I actually like the Queen, since you have the choice of when to summon them and even the choice to use pile bunker early, thus giving you interactivity that you can summon Queen to take advantage of raid buffs or to push a phase early, this is unlike almost any other summon in the game, would you argue this is "mindless" MCH play? I will admit, I think we should give Queen an extra layer of interactivity with another button or two, I think its fine in its implementation, its hardly any less engaging then the drop and forget turrets, which I liked. I would really struggle to say its way more mindless than DNC, hell I'd put it on par with BRD for the most part, I don't think 1-2-3-1-2-3 is inherently worse than 1-1-1-2-1-1-1-1-1-2-1-2-1-1-1-2, even when you say Heat Blast is "mundane" or "spammy" its still a high cut above any other of its type due to its speed and oGCD resets, making your hypercharge phase very active in comparison to any other phase of its type.
Do I think the job is perfect? Not quite, but I think a solid foundation has been set to expand upon, one that has proven popular, fun and functional. I think they can give Flamethrower and Wildfire a look over, I wish they developed MCH's debuffer skills like Dismantle and stuff further instead of homogenizing the ranged role, do I think they could have added a few more buttons and an extra layer of complexity? Sure, but given what they had to work with, essentially having to reverse engineer a disjointed, cluttered mess of a job (SB MCH) into one that's actually functional, I'd say they did more than a good job, in my opinion, it doesn't need another rework, I hope we get more as we go forward, instead of going through another set of streamlining. I understand not liking the direction a job has taken, but I think you are exaggerating its problems, I genuinely dislike the direction the healing role has taken this expansion, but I don't think the jobs are mockeries of their older incarnations, merely that I hope they seek to improve them as the game moves forward, because I understand what they tried to do, but their implementation just didn't work well with the games design (when you can beat E4S without a healer, you know something went wrong)
