Maps: prices, sell or vendor, other questions.

Hi guys, first thread, sorry if there are things which are not quite right.

I have a couple of questions and casual googling and searching in the forum did not yield useful results.

1) What are the current prices of maps in standard? I get that maps are worth whatever people are willing to pay for them (the usual capitalist market), however what are the average/standard prices? I have found several examples but they are all about 2 years old, so probably absolutely useless. My maps are sitting in my inventory, because I don't know how much to sell them for (the ones I am not running).

2) What maps should I vendor (3 for 1 higher levelled)? By that, I mostly mean at what point in levels I should stop.

3) Which maps should I run myself, which should I run with a group (i.e. not worth it to run alone)? If I don't have a steady friend group to play with, should I just go public maps? Should I charge admission? How much?


I hope you can help me, at least with some of the questions.
Thank you for your time and effort :)
