Revisiting the 10 year roadmap

[Deo14]

You make it sound like the whole conversation is just A: "Let's delete Kaiten!" B: "Okay, do it."

That's not what the quote you provided actually says.

It's still discussion between mere 2 devs, and even then, no one can say if it's sincere or another PR talk, because few sentence later, he says that it was necessary so they're not restricted by it:

Of course there are times where I thought of just flip the table and not change anything...but still...yeah on SAM's guaranteed critical, having that will make SAM's performance jump really high but there are also parts where SAM doesn't see drastic jump as they should...and on Kaiten getting removed we did that because we want to do away having to be restricted by that move, and as for its sub stats, the influence of those stats as the patch moves on will become bigger and bigger and it'll jump the job's performance really high, more so than expected and in reverse the numbers on lesser patch will see the job not jumping as high as the job should....hmmmm...Indeed, it is true that the job's strength and weakness will depend on whether the job's amount of critical dealt and I agree the job relied on that aspect too much, and as for the strength and weakness...yeah that's what it is. I of course do understand that this is part of the fun for the job....and, as for this time, we saw specific actions determined the the composition of DPS and perhaps it leaned way too much so we let some of the weapon skill value loose and we know that if we just increase the potency of weapon skill it'll result in those skills at lower level being too strong, so we adjusted on those values as well by... please refer to the new traits added to SAM located below. So...yeah, this is the adjustments for the job we made for this patch.

... just to contradict it later, by saying that it was actually for "player's enjoyment":

Well, of course I am very well aware and understand that players will feel lonely and their displeasure will get really big when certain elements of the job they played and got used to for quite a long while now gets changed or removed, so it's not like we're purposely looking away these comments with disapproval or something, but it'll definitely be much appreciated if you can tell us which part you want us to retain or tell us more on which aspects are more favorable to you after touching on the adjustments so that we can take your comment as reference, and from there we'll know where to draw the line. I'll repeat myself that we really did all these adjustments for the sake of player's enjoyment here so I'll be thankful if you all can understand this. (The rest omitted)

Last but not least, one of many "please gib feedback", even though they completely ignore it.

Still, I of course do acknowledge that there are parts where people did not ask for, like Ninja or Samurai..and regarding Samurai's guaranteed Critical, we indeed struggled a lot on the balance adjustments due to the strong ratio fluctuation here, and we really attempted to close the variance gap for as much as we could, and we know this is done for the sake of job balance so I really appreciate if you can understand what we're trying to achieve here. You can send us feedback from there and if the voices of how a job's identity has been taken away too much then these comments will act as a reference to the direction of job balance and improvements we'll be performing in the future. So please, if you do think it matters to you, do send us a feedback regarding the matter.

I assure you that it is extraordinarily normal for one designer to handle an entire class from the top-down, and for that designer to be responsible for multiple classes.

Which would be fine if that dev actually played that job.
