Misfunction detected on following scenario:

Rule Trigger: Ticket Requester Responded
Conditions: no conditions
Action: Send an Email To Technician

This action only works when just one of the implied users is a Technician. But when implied users are both Technicians, this action doesn't works.

I identified this as a misfunction because on complex helpdesk structures it's needed one Technician to create an incident specifically for other higher level Technicians (incident not related with any "normal" requester, but specifically for internal IT troubles between different Technicians). This way, the important thing here is not related with the Requester role in any way, but the email of AssignedTechnician in order to execute the action correctly.
