They've been patched to once again be affected by the Science RnD Trait but Im still seeing them crit (per my parser) below 50%.. 40% is my best so far. My Science ships run anywhere from 430-515 Epg but the deflectors seem to crit less than saw Gravity Well.
My Test medium is ISA (pug runs). Using Tac Eng and Sci Characters running a Wells/Multimission Warbird/31c Eternal.. All 3 were back to back runs.All running Deteriorating secondary deflectors (2 Colony 1 Rnd) Each did about 80k +
Prior to the fix. The secondary deflector was critting for around 60% or aleast 50%..
