When they created the FAX the triage module was taken from carriers so they no longer had 100% resist to ECM. This change has been a long time coming to fix this pain in the null carebear side.
On zkill NO carriers with sebos have been killed since the 10th - prior to the 10th it seems a sebo was almost standard fitting. No Sebo equals more mid slots for tank or damage mods which translates to more isk per tick
I know on my Chimera I no longer fit a SEBO
Edit: When I say my Chimera I mean my alts Chimera - I wouldn’t want some nd doofus thinking this character is my only character.
