I don't know that new players get better drops.. I mean, they might.. carrot and stick and all that. But yeah.. any different drop is exciting if your'e new.. then eventually you just get tired of seeing the same thing over and over and over because you KNOW there are other items which COULD drop.
And I think it'l be a cold day in hell before cosmics have the augments of 5 or 6 sets

But then.. Echo was a nice surprise. More 4 sets would be cool. Fallen... Reaper... Tomb.... Banner... Meteor... Lightning.. Zone... Quake.... Greed..
Last time they ran a "days of reward" that last reward was pretty hefty if I recall.
