Yes they increased the drop rate of crating material hugely after the army of bots preventing players from farming their own materials or do hunting logs. IT WORKED. Now the bots are gone and I can farm fleece for my own use.

The best solution is for SE to toughen up and ban players who bot. They have only mostly been banning obvious RMT with hack tools, but not players who just bot with a repeating script. The last time they did this they got a firestorm from this forum of players claiming they were banned for some retarded made-up reasons like having too much gil.

Once they decisively ban all the player bots, RMT bots and gil buyers, they can reduce the drop ratw again.
