What goes there is an event that requires a whole raid to be finished, I tried it once with group of 5 for fun but we didnt manage very long.
As far as farming goes, yeah I could have made 1500g with enchant formula that dropped for my lock one day, but I rather gave it to a friend :p
Some drops seem to be most common though, I got few nice blues and even purples in few weeks of farming, lot of cloth drops and mana motes, plus ethereum prison keys.
