You bought the Quester, WITH grinding. its only 1 file. basiclly my quester. Grinder Only is the 2nd file.
And as for questing.. it will do quests every level bracket..
6-8. does 10 quests, the ngrinde.. 10-13 does 10 quests then grinds etc etc. some areas theres NO quests
You can very easily see what quests are next by using the step editor (checking and unchecking quests.) or on screen.
