Just poor design choices on part of the development team. Moving the goalposts on the treadmill with glorified glamor equipment and cosmetic mounts instead of meaningful progression, PvP gear that you PvP to obtain being worthless in a PvP-enabled duty, rank/gear gaps with "queuing restrictions" placed over them like bandages which skyrocket queue times, how wildly disorganized the class system has become in regards to both queuing (forced party compositions) and balance (tanks masquerading as a second MDPS) - the list goes on.

It seems they will be perpetually playing the mechanic as they churn out new, unfinished venues with no forethought.
