you are right DarthRavadge, Affection are not that hard to get
as I remember it, they started out as 1 in 600 kills (just as my usealy spawn rate for T.O. carriers)
and ended up beeing around 1 in 200 kills near the end of the event
(I could be wrong here, as I wasnt realy counting NPC's at the time, but only comparing with the number of Affection with the number of Terraforming Device I picked up and thinking f... these are rare, I get the same number of Teraformers
and I always presume Teraformers are around a 1 in 600 kills drop, but havent checked my numbers for them for some time)
The Q-Pedd Assembly Line on the other hand was quite hard to get

These proberly ended up costing me around 20.000 to 30.000 kills to get those (wasn't realy counting, so it might not be 100% acurate)
think I got 6 or 8 A.I. Emotion Core before I finaly got the 2 Assembly Lines
Again it is imposible to predict how many kills you will need to get them, you can get Lucky and get them from the first 2 QPP1-L05, Q-Pedd Prototype that are shared in Legion, or you can be unlucky and hunt Down and kill 10 of them your self without getting a single Assembly Lines
yes Alex186, the havesters was almost to common this year, picked up around 200 Captured T.O. Harvester IV without getting my last Frame of Bane, keept getting Hall of Extreme Torment (Uses Left: 15) instead of what I realy wanted
so guess I'll just have to get that one Next year....
also my pressent spawn rate for T.O. carriers is proberly higher then 1 in 600
this is what I got from a quick NPC hunt where I killed 717 NPC's
(I didnt count the other uncommon, but last I checked I got 1 uncommon for every 10 to 15 kills)
1 Kulgox Entity (Special)
1 Sha'din Hypergrid (Boss / Extremely Rare)
1 Rethion, Lazuli Superhauler (Elite / Extremely Rare)
3 Silthion Queen (Elite / Extremely Rare)
2 Rogue Experimenter (Extremely Rare)
1 Lazuli Fabrication Plant (Elite / Rare)
3 T.O. Troop Carriers (Rare)4 Crimson Scythe (Rare)
1 Sha'din Envoy (Rare)
2 Dark Arms Carrier (Rare)
3 RSL Confinement Center (Uncommon)
2 Blade Harvester (Uncommon)
7 Extremely Rare = 1%
8 Rare = 1%
proberly around 50 Uncommon = 7%
that would proberly put my spawnrate for T.O. Troop Carriers at 1 in 300 to 400 instead, but "only" 700 kills so not very acurate
I'll proberly do a full 10K kills log once the Q-peed event starts that should
