robin_d_laws, explaining why he doesn't always quickly answer rules questions:
When there's a question I can readily answer in a few lines off the top of my head, I'll do that in a comment reply. However, the more interesting a question is, the less likely it is that I can dash something off. There's a reason, in addition to time constraints, why designers don't typically do rules support. Our nemesis here is Impromptu Redesign Syndrome. IRS strikes when the designer, foolishly thinking himself the master and commander of his own text, blithely dashes off an ill-considered answer to a rules query. In my designerly folly, I may think that I'm properly answering the question. In fact, unless I'm careful, I can easily contradict the more thoughtful answer that I actually took the time to write into the text, or otherwise contradict the rules as published. It's not a pretty sight when you have to errata your clarifications.
