setup group definitely has advantage which is not encourage people with hot job (such tank and healer ) to use duty finder. such as they can use 3 healers 1 tank. Can SE give solo que player a little bit advantage in the instance? such as 5% dmg increase to dps , 5% hp increase to tank and heal power increase 5% to healer? I think it will greatly help many people who struggle to pass the hard mode xxx.
