great for taking the alpha and they give an accuracy debuff (as well as damage debuff too I think)
I love them... summon them on a mob and watch them tank the alpha for you
so they arn't really that good then 
I use them as above and it works well for me. Most traps build I have seen include them too.
hmmm if you use your seaker drones for taking the alpha strike why not use your force field generator? It follows you anyways and it takes only a few seconds to respawn.
because the force field generator doesnt cause a stun, damage or an accuracy debuff when it explodes.
... worth it or not?
