If you tell it "I want 1 tank, 2 healers, 5 DPS, and no role can overlap" then you've made the job of the group finder way harder. Players aren't utilizing all the classes equally, far from it. Even during peak it would take longer to create groups, much longer. For off-peak times you'd make it impossible to create an alliance group.
To determine if that's a good idea we need to examine the purpose of group finder. Group finder's purpose is to group you up with randoms so you can start playing the game together quickly. That's it. If you add more criteria to consider, then you're slowing it down which negatively impacts the purpose behind it to begin with. Meaning, they won't do it. Your average player would much rather have low queue times and play with people utilizing identical jobs instead of playing with unique jobs and a longer wait time.
The best solution to your problem is to allow people to change class within the role they went in as before the instance begins. So a tank could switch to another tank class, healers and dps could do the same.
