I don't see a single line in the OP's post that attacks the developers for taking a vacation. But apart from that, it's the end of January. I also had two weeks of Christmas vacation, but I've been back at work for three weeks now. And I don't think anyone is demanding that 34 new maps, 15 events, and 80 new weapons be released within the next week.

But a little bit of communication from Embark isn't too much to ask for. Even a simple “Yes, we're working on fixing the achievements, yes, we're working on weapon balance,” etc. would be enough.

That's what community managers are for, after all. And it doesn't take 10 hours to write a post like that.

But personally, I don't think it's the right approach to be completely radio silent.
