Horntail/Zakum Drops: Intentional or Accidental?

I've heard that they intentionally raised the skillbook drop rate in KMS recently so I think it was accidental like some of the other glitches with the recent patches but I see no reason to change it back to the "old" drop rate

As for it being returned to normal thats up to Nexon and as we've seen in the past nexon is far more interested in money which hearing that horntail can actually be worth it will increase people "training" harder to get to go (and by training i mean buying x2 exp)

I guess you could see it that way as a way of giving people an incentive to want to train more since Horntail drops got way better, I never actually thought of it in that aspect but I believe that's possible as well. You're saying KMS did this as well? Is it still like that? I'm assuming if it is it was probably intentional and remain like that for GMS I suppose.
