Not sure why this didn't occur to me when they dropped but Ten Numb and GC? You sir, are genius.
I completely agree with the sentiment. GC on him turns one attack with Ion Pulse to a Crit. It auto goes through. No matter who you shoot at, they are Ionized!
You know, you put Veteran Instinct on him and he's PS 10. That's fantastic. You would be able to Ionize Soontir Fel as long as you can get him in arc, which shouldn't be too horrible going at PS 10.
If you are able to Ionize anyone, you can probably set them up for bumpage the next turn and lay into them. Just imagine Soontir Fel getting no actions and being taken down so easy. Then again, you just Ionize him and his range of where he will be next turn is pretty low. Ten Numb can just fire another Ion at him and get another damage auto hits. That puts Soontir Fel at 1 hull point and you know where he's going to be. Makes it pretty easy for that Mangler Cannon. Man....you can kill Soontir Fel in 3 turns alone!
Would go nicely with Stresshog too - Ion + Stress is a lethal combination for any ship not equipped with an R2 or Nien Numb
maybe cover your bases and combine the two with Blount + IPM to auto-ion any large ships you might end up facing
