Yes, another player is quiting or taking break

NMs like this are not content: they are not useful to level since they doesn't give much xp (at the level they are designed for) and they are not useful to end-game since they are trivial to down at 50 and doesn't drop anything useful.

They need to make them worthwhile of being fought at rank 30. Making them give a lot of sp at this rank would be nice. A rank 30 drop that will be discarded 10 ranks later is not nice at all.

Hell, they have that quest system, why don't they use it? Is it really hard to make a quest requiring to kill a NM without any char more than rank 35 and giving a nice xp reward?
