In ROS, raid diamonds dropped so you could make 3 Tradeskill items of your choice. In TBL/TOV they streamlined it so you didn't have to arrange for a tradeskiller to loot for you to make the item that you wanted. However, there was one big difference between ROS and the other expansions. With a ROS raid diamond you could make a piece of gear that was better than group gear, but less than the other raid gear. So a raid diamond BP was not as good as if you looted a BP in a raid chest. Raid diamonds were used as a bridge until you could get the better raid gear. With TBL/TOV, the tradeskill gear is the best. So, the entire focus is getting the muhbis/nuggets, and the other raid drops are viewed as bridge gear until you can get enough nuggets. Which way does everyone prefer? TS gear being the best, or a bridge until you can loot the actual raid drops?
