As others have explained, part of the answer is that it can be obtained elsewhere (the Lothlorien stuff at 60).

Another answer is perhaps that with the scaling to your level effect of secondary stats, as the level increases, the amount of improvement you can get by going up a few levels in armour goes down.
Finally, there was a huge amount of stat bloat at level 60 with the raid kit being massively overpowered compared to other stuff, which was unsustainable. The improvements pretty much went on hold as a result til 75.
