Social
This particular character, while lvl 85 has never been to the Moors, and does little Skimishing or Raiding, so there may be other Title categories for those 3 areas.
By comparison, the WIKI has Categories which, in many cases, barely relate to that structure. Which makes mapping from one to the other difficult.
I think the top level Category:Deeds should start out with the above sub classifications, and then expand from there.
Currently it has:
Class Deeds
Deeds No Longer Available
Epic Deeds
Event Deeds
Hidden Deeds
Hobby Deeds
Instance Deeds
Meta Deeds
Racial Deeds -- a subgroup for each race, assumes a deed is available to one race only.
Regional Deed Types
Regional Deeds -- There is (should be) one sub heading for each region. 20 sub categories .. have to count the current number of regions.
