Does anyone know what rank you stop seeing Drannik Ballistae at

They stop after a certain rank?!

I hope not, I only have three of them!

i presumed that they are only rank 200 and so once you get above a certain level you stop seeing them like with some other npcs

they dont stop and they are utterly useless

Milbrant is ranked 570 so not at that piont.

Oh, I know to take the comments of a rank 570 with a grain of salt.

I'm still eager to get my fourth ballistae

Sweet, just got my fourth at 268. Yeah, I don't know about at his rank, but they're still useful enough for me.

i haven't even found one yet, but every little bit helps.

for some reason i have only found one of these at rank 196 and 3k NPC kills .. are they really that rare?... i have found hand fulls of flux, terrafomers, and even a few quasi expanders... not to mention all the rest of the tech i could get at my rank and plenty of other goodies like toxic purifiers ect. ... why is getting the other 3 of these weapons out of my reach?

Darwin, I hope not. I'm rank 167 and right at the 1K NPC mark, and only have one myself.

they are not useless just uninstall the right before level like you do relays

I don't see how they are useless as they have the highest 'attack per space' ratio; 8.
Even the Heavy Quasi-Chaotic Blaster are only 7.364.
I got 3 of my 4 from the coordinate contacts artifact or whatever it is called.

It's quite possible he meant they're useless because they don't stop coming and you only need 4 of them; after those 4 they're useless, especially because I believe he's someone who has plenty of Complex Tech Parts as well.

I love them. I have gotten 6 so far which got me 4 for my ship and the other 2 I scrapped for the Tech Parts for missions. It sucks that you have to uninstall the weapons before leveling, but it is worth it for the extra attack.
