After some discussion, this should have been done a loooooong while ago. I've wrote up a quick FAQ on some issues we've faced over the weeks at the club, which has been sped up by the fact there's been debate over the WH/DH "Can they ally anymore?" issue with the PDF.

It's currently a work in progress, so the more questions that get asked - the more answers we can provide on here. You can also find a link on the right hand side of the page, in our handy "MAWS Links" section.
