I (Nvts) always liked to kill humanoids due to them not dropping as much ‘sell loot’ and almost solely cloth, coin, and magic items. I would look for mobs to kill on Thottbot, but it was always annoying to do, due to the huge amount of low drop percentage mobs that is within the data. Now that I have a Tailor, I have even more reason to hunt cloth-dropping mobs.
I took all of the Linen, Silk, Mageweave, and Runecloth drops from Thottbot. In theory, the ones killed the most either were easiest to kill, popped fast, or some other reason to let them get killed often. I took the first five or six pages of most killed mobs per type and copied it into Excel.
I removed all Elites, Chests and such, and instance mobs. I then removed all the lower percentage drops (typically under 10%). This should leave me with the most killed, highest rate of cloth drops.
Drop rates over 40% are highlighted. Tables are sorted by level by default, but they are sortable by any of the column headings. To reset, simply reload page.
