So basically this is all working as intended.

Trust system is mostly there to get the DPS through the MSQ as fast as tanks and healers can get through. Save for trials, that seems to have been achieved.

Tanks and healers shouldn’t be using this feature unless they just want to see it. They can get into and through groups a lot faster with the duty finder. Making the system agonizingly bad to use as a healer or tank is a good thing; it encourages them to stay in the duty finder and lower queue times. Allowing a DPS to speed run it by just being good encourages more DPS to get out of the duty finder; again helping to lower queue times.

So, successful system from the looks if it.
