Dungeon is easier to just do during power hour. it will take you forever to get to GM just macroing on 1 or two boxes. I used this macro while training in the dungeon. Just set a macro to stop and clear alias 'chest' so you can do it quickly. Just run from chest to chest during power hour and open or loot, you're only doing it for gains.
My dungeon rotation was Cove 4 -> Despise (all lvls) - > Shame (all lvls) -> Ice -> Minax
I would just run up to each chest, invis, pick, run to next chest without looting. That way you maximize your gains during PH. I would routinely gain 1.5-2.0 during power hour.
PS. I want your justice house!
