Very expensive, might work fine the first couple times you tried it but after a while dumping a thousand credits into creating 5 seekers at a time and then just ramming them into something does not seem to be work the damage output.
If it's anything like the damage output of Brilliance + Malice, it's well worth a thousand credits, since Brilliance + Malice can sometimes destroy an entire fleet. That's definitely worth a thousand credits to me.
