As far as I know the only title in question is the HW title, which the only defense that has been "dictated" by the WAC is the last defense against "Maple" who is Teshore's guy who had 2 in a row, but apparently Wun had 4.

When I was given the rules by GF there was no mention of dropping titles, and with all of the old threads being deleted in the server switch I'm not sure if this was a rule in past.
