But serious bugs should be solved as soon as possible even with the current staff.
That is most certainly what the BB team tries to achieve.
The communication of the problems has got worse for last few months even if there are 2 BB's that was named especially as public relation BB's.
While I don't agree with this statement, I think there is one obvious explanation for what you may be seeing. When you work on something, you know when and what you can communicate. Going through a second person will only slow the communication some. Instead of one gate, you have two gates for the information. For communicating on bugs, this can easily mean additional delays. As the game gets bigger and as the team gets bigger (+ more and more people work in different locations), it becomes more beneficial to take that extra time in some cases, basically to let people work on what they do best.
Overall, I think the communication has improved in areas where one can expect the extra people to contribute. Communicating on bugs and delays has remained quite unchanged in my experience. It may have slowed down a bit in some cases, but also become more thorough in others.
