You know, if you get "The Insane" title, at least you can go around bragging your total waste of time by having The Insane title next to your name.
However, I don't understand the point of making Nat Pagle rep almost impossible to farm. I spent 5 hours yesterday out of pure masochism fishing pools around Krasarang to see what the drop rate for the quest fish was, and I didn't manage to get a single one.
At this rate I expect to reach exalted with him by the year 3752, give or take a few centuries.
And for what, for 75 more fishing from your lure? This is ridiculous and ultimately pointless. I can fish Jewel Danio without 825 fishing just fine.
