Lucky me. I guess as a Level Designer I can keep commenting on none serious posts. See what I did here? ;)
Jokes aside, if there is an issue where it makes sense to engage with, we do. Especially if there is an issue were we need more information on it, but normally if let's say a bug is found and posted we take it and forward it or fix it if it's our area. As an example, I took the issue where two pre-round spawns on Marita Frontlines were up in the air (players falling from the sky at the start of the round) and fixed it today. Yet, I normally don't comment on it. For one, there isn't really a point - actions matter more than words and second, it's difficult because even if I would say I fixed it as I just did, it takes weeks until it arrives in a patch (testing, console verification, patch dates, etc). Besides, we haven't be too good with sticking to our promised dates lately. 😅
So at the end of the day it really depends on the issue,but rest assured, we see most of the (upvoted) posts here.
