These quests can be used to level alts without leaving your capital city, as they can be turned in directly from the quest log:
In case you're looking for a macro that allows you to automatically turn in the 5 auto-complete quests (to save time on the duration of [item=86574] or [item=128312]), this is what I use:
/script local ids = { 31851, 31819, 31850, 31780, 31781, }; for i = 1, 5 do local index = GetQuestLogIndexByID(ids); SelectQuestLogEntry(index); ShowQuestComplete(index); CompleteQuest(); GetQuestReward(); end
You'll have to spam the macro, but it'll be done within seconds. Remember to disable all addons to minimize loading times as well! ;)
