I'm a boxing 92 chanter magician combo I can finish the steels and blades quest about 4 times a night if I grind about a hour each time for both, both have 2000+ aa . I have another bot 88 ranger. Ranger get 2% per quest but i get 12 aa off two quest for 92lvl. It isn't simple in the sense of finding all the different creatures for the quests. waiting for there stupid random spawns to pop the one you need. Empowered blades ive noticed can be the most annoying. The belly near pillar named can get you the spawns you need and if you have a sold group effort you could spawn up to three named. Take away the nurf so I don't have to grind mobs in area so hard to complete these quests faster or make static spawns that don't change ever 20 mins to something else...
Overall for the level im at i can grind out over 115 aa and 4 or 5 named in 4 hours.. pop a two hour potion you do the math lol..
98 bst there are a few easy quests in t4 zones. City of bronze
