The following measures will be implemented on the 17th (next maintenance):

- The upper limit will be raised on the (hidden) points you get for killing enemies that increase boss drops. (Presumably this means the maximum number of boss drops will increase)

- Anga's (hidden) point value itself will be lowered.

So if you ignore the mobs and just kill Anga, you will get less drops than before. If you stay in the map for a long time and kill plenty of mobs you will get more drops than before.

- The number of mobs that spawn together with Anga will be reduced.

This is to prevent people from just killing the mobs that spawn with Anga for points.

- Once you clear the quest, if you enter the campship you will not be able to return to the map again.

This is to stop people from farming the maximum points and then just waiting in the campship until Anga appears.

Considering that people already farm up to 100~150 points before killing Anga, these changes don't seem like they'll affect dedicated Anga farming parties much (unless the third measure is so drastic it becomes impossible to farm mobs while Anga is on the map). They are mostly geared towards stopping ship campers.

Also unrelated to Anga farming:

Rappy, Umblla and Nyau emergency trials will be removed from Ultimate, so that Ult-specific trials will occur more frequently. More mammoths for everyone!
