The free 280 hp gems etc have been removed. The bosses will now drop the Perfect series of Augs that was not in game until now. Also, Bosses in hard will keep their chance, albeit very small, to drop something from the Uber Loot Merchant (which can be sold back for points).
About points - its been said that Hard takes 3x as long as normal.
Lets see - Normal = 30 points versus Hard which yields 75 points. That's a factor of 2.5 right here. Combined with the much better augs and the uber loot chance, i consider this very well balanced now.
To the Hardcore raiders - please keep in Mind that the Ancient Frozen Armor also has a type 1 slot and Hard Ldons having by far the best Type 1 augs in game.
