Well, QA definitely reads the bug report forum. Forzaa and DDRJake post in there reasonably often. Based on the content of those posts, what they do is log verified issues internally in whatever bug tracking software PDS uses.Considering at least a chunk of the suggestions are basic improvements to the game's user interface, no.
I find this difficult to reconcile. Either they aren't reading many of these posts, or they read them and log the bugs, then decide that they're sufficiently low priority to take a back seat to both new DLC content *and* the numerous changes that make the cut and get implemented in the patches.
It's hard to believe a developer would say "yeah, re-assigning how AE is distributed in some subject situations is way more important to change than a flagrant user interface lie that was clearly documented and readily reproducible", then go on to ignore the latter for two major patches. I think it's actually more generous to conclude that they don't read that forum carefully, because the alternative conclusion is pretty bad.
Thing is, something like a UI mistake probably gets classified as a minor issue in terms of importance (because it doesn't cause crashes or interact with other game systems). And I'd be willing to bet there are hundreds of "minor issues" sitting in their internal software at this point.
Beyond that, fixing a UI mistake that's present in terms of wording is actually probably harder for a programmer than tweaking something numeric under the hood. That's because the UI is localized into many languages, so properly fixing any such issue means having the text checked and potentially tweaked in all the languages. Probably PDS uses contractors for at least some translations; I'm not sure they're big enough to have full-time translators in-house, and I don't recall ever seeing them named anywhere if they are there. That would make these kinds of fixes expensive, so what you'd want to do is try to do them alongside other work you needed to have done anyway for some paid DLC feature in order to minimize costs.
Not to sound like I'm making excuses; issues need to get fixed. Just, it's probably more challenging than it may seem upon initial consideration, even if I'm off in some of the details.
