in addition to the quest header do a check on objectives for what zone they are in?

also check the header group of the quest for zone name? i.e. the pvp quests are in the "Valdrakken" group - how can i use that?

(just an idea)

V1.3.5 added the ability to check the quest header group name. V1.4.0 further optimized this check.
Quest objectives do not have zone attachments so can't be used.
