Firstly, there's nothing wrong with letting off steam etc. as long as it's presented in a constructive and concise (if possible) way. We need to know what is specifically the issue, and how you believe it can be improved.
If there are several threads that are all about the same topic, it's a lot harder for us to collect accurate feedback for the devs. It diminishes the quality of the discussion too, because a good point raised in one thread will not be seen by everyone discussing the matter in the other threads. It also means there are several small threads instead on one big thread, and smaller threads tend to sink faster on the boards, so less people will get to see what's been said. Therefore, it's better for everyone if there's one main topic where people can discuss things.
along with other criteria such as mentioning Blizzard in the title(why that tho defeats me tbh)
It's not allowed if it's only done to draw attention to the thread, e.g. "Blizzard read this". But if it's discussing news etc. it's okay :)
