If I've developed some home-brewed content for my favorite RPG, such as a new class or monster for a d20 system, would posting it in a question asking for balance-related feedback be appropriate? While I believe it is certainly on-topic to the site, I fear a few things.
Most importantly I fear that it may lead to too subjective of answers, even though the question would be phrased with the intent of generating more a objective "yes, this is balanced" or "no, this is broken: fix ____" by comparing the content to similarly powered core content. I wouldn't be asking for stylistic or flavor feedback, but rather answers such as:
You basically took a wizard and gave it perfect combat stats; there's no reason one would choose the core wizard over yours, therefore this class is broken. Reduce their spell-casting abilities to force players to make the trade-off.
Another issue is the fact that most class rules are far longer than typical length questions, and I would be tempted to post a link to them, which I know is frowned upon in case the link breaks.
