I rather enjoyed having to really work for getting those books, although it took me several weeks.
Plus it would be one of those things that would be REALLY upsetting to see in shops or even in raidboxes for people like me who made the effort to get them mostly by themselves.
Sure it's taking time and effort, and yes it IS depressing when you finally get there at respawn time and then 10+ people show up. But it is not impossible.
For people here still wanting to try getting them: If you just farm at gate 4 instead of e.g. ruins, you`ll be there at respawn.
Even with 10+ people you can still get something out of it, as what`s important is the damage you make on the boss, not the number of people (if I remember correctly it`s 10%)
