So here's the thing, I LOVE PoBs... but there were way, way, to many of them all over the place serving no purpose other than as a vanity item for long time or wealthy players. I like that they take much more effort to maintain, and that the clutter is clearing out. It makes the market and economy better for the PoBs that are active.
Admittedly the current PoB economy-system is definitely in need of some major fine-tuning, especially in the areas of PoB upkeep cost (effort required good, insane budget upkeep not so good compared to the output) and mining viability, but keep in mind that this system is also brand new. I really enjoy the general direction they had in mind.
Fewer more-actively maintained PoBs is better than a larger number of abandoned ones.
