At least for leveling crafting without burning too many millions of plat.. High lvl random junk loot seems worth getting again (to subsequently destroy.. Even if you dont like to craft, other that do will buy it on AH, or buy the essences you may get)..
I was mainly selling red scales for a mil plat and doing it that way.. But it seems our economy has shifted and I can't get a mil for a red scale anymore. So as profitable as dragon runs are, maybe its worth doing a lootrun..
I guess some people might say epic, but other then for guild renown.. Epic loot is actaully ****. Generally lower lvl then regular high lvl loot. (Usually youll see ml12-14 items, very rarely 16.. While lvl18+ quests youll find lvl14-16 commonly, rarely 18, and possibly even 20 for lvl23 + loottables (mainly just tod atm, tho DD elite may qualify with a lootgem)
Then epic quests tend to take a bit longer then normal-elite ones too.. So epics mainly out of the question...
Tho for a easy solo lootrun, DQ1 epic remains pretty good. (3 chests in 3-5min if you have another account to do resets)
Raid wise, Shrouds the obvious winner at 12 lvl17 chests, with groups generally being fast to fill/complete.
Non epic/raid.. I'm thinking IQ/DD.. They were always the easies/fastest high lvl quests, far faster then amrath ones, and some have lots of chests. What do you guys think?
