There is a huge range of different questions available to ask about alpha/beta. I'm not entirely clear if knowing this would be "incidental knowledge" or "Expert knowledge".
In any case these questions will still need to comply to the other parts of the FAQ/Help Center.
I don't know anything about your first question, but that might be because I don't know anything about the game. This question has to be evaluated to be incidental of expert knowledge since I'm also not sure that knowing a lot about WoW will help you with knowing this.
Your second example question would be off-topic. Because it is basically a shopping request.It also has a problem of having a very time-limited scope, since no answer will ever stay correct for long. And neither of those are allowed. (I can't find the time-limited scope in the flag for closure reasons anymore though)
