Sometimes it helps to identify what role a unit has, e.g when checking the group for a debuff and wanting to know their role before making role-based decisions like assignments

Describe the solution you'd like
%roleIcon or %role as trigger replacement that also works when the unit is provided via TSU

Describe alternatives you've considered
