This concerns this question, but I think we can have a discussion more abstractly.
What are the restrictions on asking about preparation for future content?
In this case, there are a limited number of acceptable answers (less than 10 ways to spend gold on D3). The question is about current content, and not the content of the patch/expansion. Other games, (such as apparently D2) have experienced a similar trend, so users can draw on experience to answer.
What are acceptable requirements to have a question about PREPARING for future content, or does this wholeheartedly fall under the 'no future content questions' rules?
