As for the argument its too powerful at the moment to be on the store. Yes its powerful, but as I said this item bring melee a pure %dps increase, whereas other trinket bring a fairly static dps increase no matter what your gear is, making DST what it is. The overpowered component for its ilvl is certainly here but its only partially why it remains BiS so long. All that to say that atm, DST may only be at 50% of its maximum potential (as said before the more gear you get, the better dps increase it brings), and while still being currently very strong, its not as overpowered as you make it to be (if it were all top logs would be filled with the people that have it atm).
