Why is HM primals 90% drop rate BOOKS(SMN/SCH)

Make it fair for everyone...

ive only seen 30% dragoon weapons so far.

hardly any books, No bows

Up to about 80% DRG harpoons

I once joined a Garuda farming party. We killed her about ten times. Seven -- yes seven -- warrior axes dropped.

Because you don't understand probability

It's not even a bug, just some rant by person who probably can't get their weapon. This doesn't even belong in Bug reports.
Besides, it dropped pretty much evenly for me.
