After experimenting the best I can with the times I noticed that all my DF roulette have ended in 1 Tank, 1 Healer, 1 Melee DPS, and 1 Range DPS. On MSQ roulette I also got 2 Tanks, 2 Healers, 2 Range DPS, and 2 Melee DPS. If this is a "tweak" then that would account for the increase in time. Harder to get an exact DPS setup then just any DPS that is on the list.
