I doubt that the changes will be able to see what itesm you have already. so in a case where an SK with full Fabel gear hits an instance, SK gear that istn an upgrade my drop. In that case youll see that stuff hit broker. in a lot fo ways, you may see more stuff being sold on the broker. If it works the way I think it will, everyone will have their sets a little quicker, and then the rest will hit the broker. Anyone who can afford to buy the gear will, and then if they group and something drops that isnt an upgrade it will go back to broker. Prices will drop, and more people will be able to buy the gear.
IMO its something that should have been done a long time ago. Id also like to see multiple items dropping from master chests again. Im tired of raiding zones like Freethinkers and getting ONE fabel item, and MAYBE one Master spell. 24 people in the raid. 4-5 mobs in the zone that drop master chests, so 4-5 people a raid if your raid can clear the zone will get an upgrade after spending 2-3 hours in a zone maybe, if not longer.
