I share exactly the OP's thoughts.

"Look forward to it!" is a catchphrase that I started to loathe, and is basically what we have regarding whatever is coming to 8.0's jobs.

But come to think of it... to actually look forward to something, we need some sort of reference, right? For jobs what is the reference we have? The rolling downhill that is been happening (more like a plummeting in DT) ever since Shadowbringers. How can I look forward to jobs in 8.0 when the CBU3 developers (and Yoshida green-lighting it) are the same ones that did the recent job changes?

Do they mean that I have to regard all of that just as some provisory fix because the real deal is coming? What is? Without communication, it's impossible to think positively about this. And by that, I don't even mean sharing specifics "Hey look at this new PLD resource gauge!" but at the very least the design philosophies that you have in mind. It raises a lot of questions to the director, such as:

Are you happy with the design brick wall that healers have today?
Are you happy with how almost superfluous the aiming role jobs are today? Are you even planning new aiming jobs with this scenario?
Do you truly think that the 2 min meta shackling the job design is creatively good?

We need communication. A 'Dev Talk', a letter, anything! At this rate all they are offering is the "Look Forward to it" that can be read more like a "Trust me bro".
