Interface for Dark Blast/Force Field Corruptor

[Lunar Ronin]

I have a level 50 Dark Blast/Force Field Corruptor.  With Power Boost he can give teammates +44.3% defense, and then there's the -7.5% to-hit debuff from the various Dark Blast attacks.  I.e., he can softcap defenses of everyone on the team by himself.  I always take two Interfaces.  The first is Reactive Radial, and then a second because so many others also take Reactive Radial.  I'm thinking either Diamagnetic Core for the second Interface, for the extra -to-hit debuff on top of the Dark Blast attacks' -7.5% to-hit, or would that be overkill?  The other choice I'm leaning towards is Degenerative Radial.  Thoughts?

Diamagetic for sure. A lot of people never take it so odds of it being nullified is lower on raids.

Degenerative Radial for maximum effectiveness.

 

Diamagnetic Core for maximum -ToHit meme (which gets slashed by the purple patch anyway).
