4th Job Warrior Rush Storybook

Hi! I'd like to raise the idea of possibly making it a little easier to obtain the "Indecipherable Book" Storybook from Taurospears, which is required to start the quest to get the Rush skill book for warriors.
I've heard a couple other 4th job warriors describing the process of getting the Storybook as tedious and soul-crushing, after they farmed it for 30 mins-2 hours. (With me myself posting this thread after farming for 4 straight hours on Taurospears with nothing to show for it. ._.)

The problem being is that the Taurospear spawn is INCREDIBLY low, with the drop rate of the storybook also being seemingly low. The only maps that naturally spawn them would be Dungeon:Sanctuary Entrance 3, and Sanctuary Entrance 5, with SE 5 being the better one of the two with a whopping 5 Taurospear on the map at any given moment, mixed in with a bunch of Cold Eyes and a couple of Tauromacis. They also spawn back kind of sluggishly too, though I can't tell you how long without sounding very biased.

I would like to suggest, if possible, that the Taurospear spawn either be tweaked to provide more chances to receive the storybook, or to increase the drop rate of the storybook. To how much it should be tweaked, I wouldn't know what rates would be fair, but I feel the current state of it feels a bit...tiresome. Mainly because I'm so unlucky that I haven't gotten anything in 4 hours straight... :S

Maybe I might be whining too much, but I'm curious to know what everyone else thinks. Of course I'll probably have it by the time this post is decided on anyway, but it'd probably be helpful for any other up-and-coming 4th job warriors. I've also added a poll.

(EDIT: I just got one after passing by the map on the way to Jr Rog by killing one Taurospear. Go figure.)

 

This is a pretty good argument against it, I hadn't even considered that. Judging by everyone else's responses, looks like it shouldn't be changed and I concede the point as well.
