You'd literally just see:
Achuak'iejir Stormwind (Disguised)
-if I was to wear a disguise; instead of, say;
Dark-Armored Woman (Disguised)
Nowadays, it just leads to needless instances and excuses for the metagame of a well-thought out guise (and - subsequently - reduces the importance of a well-thought out guise, since people are gonna act different around you/roll spot-checks incessantly by virtue of what they see anyway)
Add to the layer of mystery some! Remove those bloody tags.
