It's nice that the spawn rate of a boss has been improved but i find it really too much. I cannot no longer train in the hidden map zipangnu without having to be killed by the boss Black Crow every 2 minutes because i am still low level. So because of that, i can't level up no more in peace since he would be there in every possible channel. Would it be possible to have only a few bosses spawned, not all of the channels having to be preoccupied by one?
Crow's spawn rate is 12 hours. The only problem is they respawn upon restarts right now. If you need someone to kill them, just ask a higher level. Most have no problems doing so.
