Well there were a few symptoms of the problem as I saw it personally. Those being:
A) Simple maps were being sold for prices the 20's, 30's etc tier people wouldn't really be able to afford. Standard price was about 75-100pp each. Not too bad as the recoup rate on 30's is about 30pp 40's and 50's is slightly higher, and pretty much why they were running at that as well.
B) The prevalence of them was possibly adding to concerns about the market for droppable gear and tradeskilled gear (to a lesser extent in some cases).
C) Droprate seemed lower than for ve e maps tbh.
I don't think the fix really helped things at all personally. As it is now, go ahead, try and find a map 20-59. I bought the only one actually on the market the other day. For 200pp. Now as the situation stands, because so few people fish (as it is boredom supreme, not sure about the fishing droprate, but I'm assuming it's dismal, always has been with fishing), and they are so rare (paw clear with imeriaz, not one, 2 hours in cc, not one, etc), the price for them has inflated so much due to demand that while lowbies could have just pooled their $ before and gotten one with a decent return on their plat, or could have actually gotten one in the course of a group, the chance of them doing so now is pretty much null. Any of the ones getting done were probably due to the direct intervention of twinks. Seems like the previous situation was alot better tbh.
