There may be a wider selection of weapons at 60+ but most are not available on the AH due to crafter's not making them anymore. You gave us a nice selection between 1-59 and then nothing after that, it was frustrating trying to level PUP in the 60's because your next best weapon was never on the AH. I shouted for 6hrs before I finally got a crafter to make me some Tigerfangs just so I could get a new frame.
It's good that you're finally going to fill the gap between 60-99, although I.m not sure why it was there to begin with.
