You are continuosly not hearing the community
I think that its important to note the difference between "hearing", "acknowledging" and "acting on".
You can see, near the bottom of the page, who is looking at what thread; and I've seen "Sander93", "Andy_RE", and others pop up in a
lot of threads. They're clearly going through community feedback, suggestions, and other posts on a fairly regular basis.
With that said, they're not going to
act on (or even acknowledge) every suggestion. A significant portion of the community suggestions are either not entirely thought-out (ex. makes sense in 4v4, bricks 1v1), impossible to implement (ex. game-mode resource scaling, SturmTiger rocket arc, etc.), or would cause further imbalances (ex. buffing already strong units).
Considering the number of these suggestions, they're not going to be able to reply to every single idea/comment/thread with a detailed response; and simply replying "no" wouldn't go over well with many forum members. As a result, staying silent is the best response in a lot of cases.
However, I think its becoming apparent that there is some degree of communication breakdown between devs, the balance team, and the community. There are several "hot button" issues within the community that have been coming up repeatedly, for months on end, that simply aren't being addressed, or even commented on.
Let's take the M36 for example; some say its drastically over-performing, some say its just a bit too good, some say its completely fine, and I've even seen some say it could use a slight buff. Regardless of opinion, its clear that a large section of the community has issues with this unit - so what is the balance teams stance on it? Even if the next patch isn't changing the unit, a statement would be nice. Something like:
We've seen that the community has been talking a lot about the state of the M36 lately. We wanted to chime in and let everyone know that while the upcoming patch doesn't have changes directly aimed at this unit, we have been discussing it internally. While we think that the USF needs a strong late-game TD to counter Axis heavies and super heavies, we've seen that the M36 is performing a bit too well against medium tanks. In a future patch, we're hoping to test a few changes to lower its performance against medium tanks, while keeping its performance against heavies.
*The above comment isn't real, and is only meant as an example of what a statement on 'hot button' issues could look like*
It would likely be beneficial to everyone if the balance team picked several of these issues, and wrote a "Q&A" type post covering their thoughts on them, even if it was only at a 'high level' like the above example (i.e. no detailed stats or promised stat changes).
Similarly, some of the more recent changes don't have an explanation, but also don't seem to be based on common community complaints; such as the On-Map artillery pop decrease, or the reason for not adjusting the Pershing's AoE along with the other Heavies (in the 1.2 patch). And, of course, a comment on (possibly) unsuccessful trial-changes (i.e. OKW's IRHT) would also be beneficial.
TL;DR - The patch team is fine, but better communication would be nice. Maybe bring on someone (or give the roll to someone already on the team) to do community FAQ/Q&A posts?
