Pirates keep spawning in mission?

[Battleseed]

Went to the Distress Signal and it turned out to be a pirate lure. OK, so I fight and kill a couple but then more warp in. Kill some more and again more show up. Bailed on the sector as I wasn't gaining any ground and not able to get the pickups from the ships without letting the rest shoot me. Did manage to lure the group away once to double back and get the drops but wasn't worth the time it was taking.

Took a board mission to kill some pirates. Head to the location and there are 7 pirates but spead out across the sector. Engage and blow up one, but as I finish him off,all the others have almost reached me. I kite the pack around and pick off the faster ones as they chase. 2 near dead, and then another 3 warp in. Sigh now there are 10. Dafuq is with this constant spawning? Do you have to do these missions when you're OP for the sector?

The spawn cadence is variable for warp-in's, they can be pretty much back to back, or have 30 minutes or more in between them.

It's ok to duck out if your ship cant handle the whole fleet battle- the drops shouldnt despawn for quite some time and you can go back and knock off the remaining ships at whatever pace you need.
