If you have 3 purple torpedo doffs assigned, quantums are better than photons as the doffs will most often activate with 3 chances at 20% each to remove 5 seconds on a 9 second cooldown.
Note that the doffs will attempt to proc on every torpedo launched so High Yield 3 will result in all 4 torpedoes attempting to proc 3 times each at 20 percent. and it only takes one to reset the cooldown.
The borg proc is broken for the most part. Most of the enemies are immune even though they are suppose to happen every time.
If this is true it really sucks. The [borg] proc with turrets and cannons is one of the few ways a cruiser can really excel at STF's. I'm not a "cruiser+cannons=win" person but I use to swapped out rear weapons for [borg] turrets religiously while STF grinding.
The ground proc is 100% for every anti-borg weapon. The space proc is 7.5% for every weapon EXCEPT projectile based ones (I.E Torps, Mines etc). Those are 100% proc for the Borg radiation on paper. In reality I usually have my torps proc at a rate of either 50% or 66%, so 2 out of every 3 torps, or one 1 out of every 2 torps.
On ground it definitely works -- I'm not sure why it'd be different for space.
I agree the ground proc works perfectly but not all space borg are proberly affected.
If you use a borg torp in a borg dse or story mission you will get a "Chaotic Particle Stream" for 1000 damage.
Whe I did the test in ka the only time Chaotic Particle Stream appeared was with the Nanite transformers and the Donatra's Ship's officer Tractor Probe.
The proc did not go off for the tac cube, probes. spheres, nanite generators and Donatra.
I found a thread from January showing this as well but it was never fix. I only found out about it when I was trying to figure out if the borg transphasic would to more damage then the rapid fires for a sci build. on a torp boat with 3 borg transphasics on the front and 3 projectile doffs the borg proc only went off 95 times on those 2 enemy types and nothing else.
