Mobs respawn too quickly
This should probably be in the bugs section but yes, mobs do respawn too fast. In fact they can respawn instantly, literally upon the instant you kill them, so they couldn’t possibly respawn any faster. I’ve seen this in numerous zones recently. This is for normal open world mobs as well as mobs related to events.
it’s also a big problem with events, particularly “capture X place” ones.
As best i can tell, the mob spawns are not bound by location. They will instead use any available spawn location assigned to their kind.
Meaning that the mobs spawning inside a cave may well be mobs you yourself killed on the way to the cave, if they are of the same kind.
In the past there were known places where there were multiple spawns for one site. If you are seeing immediate respawning, it may be that and you can report it as a bug.
Other than that, it would be nice if they lengthened the respawn timers a bit. When there are multiple mobs and a champion it can be a problem if you are soloing.
