I'm actually surprised that they didn't remove the items from the previous prestige & destiny packs. It wouldn't be the first time that they wiped inventories of boosts, even though we paid for them. (Somewhere in the fine print they reserve the right to do this.)
At the end of the day, we all know this is a money grab. The only question is, who does it help? I'm happy to plod along in my mid-grade gear, which is quickly becoming low grade, because L grade stuff is around the corner and I can barely get a +10 R110 bloody/dark set, let alone a +30 to upgrade. But I have been playing since C1, so this is kind of like a 50-year bad marriage that people stay in because divorce just gets you an empty house with 4 blank walls. I do not know how you win new players this way. And I doubt they will be able to keep old players for very long. Only real-life wealthy people are going to empty wallets for this game, and that's a very, very short list of players.
