It would be very useful and probably easily coded feature if we could select a
classification for ourselves that can be searched for with who. Examples would
be healer, offtank, conjurer, habotank, reincer. A few of the ranks availible
seem to be there purely to mimic what I'm asking for, such as merchant and
mixmaster, so I'd say the precedent already exists for adding this feature.
I'd say there are about 15-20 common designations that people are often
looking for, and being able to display one's preferred role through who would
make gameplay more enjoyable for many people.
