You’re misconstruing the situation.
There’s some principles we know they try to abide for in modern WoW balancing.
First, they try to make all dps specs do about X damage regardless.
The point being that every spec should have the opportunity to achieve the hardest content.
The DPS charts aren’t a perfect tool.
The lowest performing class aren’t really that low.
Now it doesn’t mean there’s never any outliers, there are, but usually it gets ironed out a week or two after RWF ends.
Ret is not an outlier ATM, in fact its average performance is always a bit inflated on raid DPS chart by people dying and triggering Instrument of Retribution.
Now, this specific tier is absolutely PLAGUED by bugs and quality issues that makes the charts very unreliable as well.
Secondly, in relation to the first point, they don’t really “care” where specs generally end up on this chart as long as it’s within their parameters.
So if your spec happens to not have any bugs, within their DPS range and there’s nothing really wrong anywhere else. they won’t touch it much.
Ultimately this is may be the best situation to end up in because they are often horrible at balancing stuff right on the first go and we end up with situations like Fury warriors.
Thirdly, the different specs are supposed to offer different type of gameplay and it include complexity in that, for better or worse.
Personally, I think this is fine up to a certain degree but if I need to become a pianist to play a spec then I think it becomes a problem.
PERSONAL OPINION
For abilities that you will use as a rotation in combat and semi-routinely (stuns, kick, etc)
I think a good balance to strive for, is to aim for around the same amount of buttons a modern console controller has, and by that I mean with modifiers so around 20 key binds.
(I’m not playing with a controller, it’s just that I feel the console format really evolved throughout the years and I feel their perspective has some value in term of mass appeal).
Finally, if anything, Ret current gameplay design should be an example to strive for rather than a target to shot at.
They don’t play correctly then.
Beside, I get the weapon is a big deal but there’s also like 14-15 other equipment slot beside the weapon soo…
This might be your anecdotal experience but nothing more.
