I have searched and not found anything on this topic. I don't know if it's an issue with my account, the game or what. Twice in two days I have queued as a healer for a MM FP through GF. Once as a sage consular healer and once as a scoundrel smuggler healer. Both times, I was only queued for heals and I was only queued for heals from the time that I logged into the toon until after I had queued. I didn't change from a dps/heals or dps queue to heals and use the user interface hack to get the program to recognize that I had changed my role. I was heals from before I logged in as the toon. Both times, when the MM queue popped, I was given a dps role. I did go ahead and respec and change my gear and dps but the group was rude about it and I don't know how to stop this from happening again.

Are you sure you didn't queue as both DPS and Healer? For classes that have the dps/heal or dps/tank choices, there is a checkbox that defaults to both if you don't select one. This is not dependent upon your current config.
