Like I said in the other thread, there is many large tree you can use to kite around and hold forever. The closest one you can use is in front of the Aern mission tower, near the quasilumin.

Most NM depop 3min after reaching their spawn location, but it's different for JoP. Its spawn point seem to be the position of the 2nd prudence, not the "???". Once you kill one of them, it's still going to swim in that direction, but will despawn 3min after losing aggro
That's how I unerderstand it, but I might be wrong since JoP has one of the weirdest behavior
