It's a lvl 4 device, so it would be fitting to drop off of a CL 20ish mob. Add a few of them and make it a group fight, but no way should it be on a CL50+ unless it changes to a lvl 8 debuffer.
This is glaring evidence of the lack of plasma debuffers, notabally the pulsing bullywhere eye, and the recently removed hellbore (no RD base). Right now you have a Jenquai only device (Chimera?), and a Progen restricted device (Rada). Debuffing options in general are bad, with lvl 150's using a lvl 5 taniwha for explosive/impact, a lvl 5 rada for plasma, etc. I don't consider chem a viable option given that 2/3rds of a mob is shields for mechancial, and 100% for bio/organics.
