Show region quantity per items
Sometimes, Region Market Avg is calculated based on 1 or 2 items on the whole region.
Having the region quantity showed on tooltips will be very useful as a way to review the accuracy of Region Market Avg. It's a kind of "weight".
-Seeing a very rare transmog at 2k gold Region Market Avg, with 1 quantity in US, shows that in fact there's high chances that it's a very valuable transmog.
-Seeing a transmog at 16k gold Region Market Avg with 453 quantity shows that this price is indeed very accurate.
Now as a value source. Required to know if an item has an accurate pricing
Here is an example, the Natural Ward : https://theunderminejournal.com/#eu/aegwynn/item/31399
So, at the time we have to actually think that the price might be non accurate (could lead to mistake in the flipping market) and check a website like TUJ to see that the EU quantity is 2, meaning that the region avg price of 55k is not realistic.
The undermine journal manages to get a realistic price though, somehow.
Having the number of auction is really needed in my opinion.
I also think we should be able to ignore a pricing if the EU quantity is too low.
