Just something that I was thinking about. I do not have toons all that high (monk just now is nearing 40), and I am doing mostly solo stuff other than LDoNs.
What was the best single item drop or quest that you did solo?
So rule out anything you needed a group to get and won a roll, or bought or was handed to you. It may have been luck or perserverence but essentially YOU DID IT! No buffs (other than self) or extra special equipment is a PLUS! Uber-ness of item is not necessary but SATISIFACTION is.
I'll go first.
My 18 Monk got a Goblin Gazughi Ring after killing the Sarnak Courier in Lake of Ill Omen. Got it after the 5th kill, and haven't seen one drop since (maybe 30 more kills with various toons.)
This item currently resides on my 34 Druid and is just a fabulous tool to have when there are aggressive animals about.
(Just try to med in Iceclad or Stonebrunt without Camo and Hide is a pain to stick sometimes.)
