Deciding on my third S-rank right now. I have a Demons Mech and a Hell Needle. I'm considering a Zal Gun, Demon Needle, or Arrest Needle/J-cutter. Zal gun seems like an easy choice because my RAmar and new HUcast can both benefit from it in solo play. However, Arrest J-cutter would be really good for my cast and Arrest needle good for my RAmar. How is the activation for arrest needle on RAmar compared to J-cutter? I tried Arrest J cutter on my HUmar once and the fleshie activation was kinda crap and not reliable enough to be useful. Thoughts?
