DQ counter for how many time you Supp. After so many, you auto get primary role. SOUND GOOD?

Lot of people get complaining about fill and support in dynamic q. I was on a roll where I got a mix of primary and supp secondary. Now all of the sudden I am on a string of support roles. There should be a certain number of times you get any one random role before it gives you your secondary role. 5 times in a row is a bit much.
