In evey LDoN advanture I have done, the group has wanted split off and do a split at the end. In normal XP groups, they normally want it left on. In LDoN, I have had a ML bolt on the group once, not only with the split, but with the named drop, an architect's bejeweled chestplate. The group was very angry about that. I think the best srategy if you are ML is to ask what the group prefers and go with it.
