What does PQ mean? I see a few mentions of it in the forums but couldn't find a definition with a quick forum search. Also doesn't help that the search function excludes "PQ" even if you put a "+" in front of it

Further, any suggestions on how to quest or questing add-ons for low level PvE? I find it a bit hard to find where on the map(s) I'm supposed to go to do my quest objectives.
Thanks!
