The Sensor Strength bonus buff to marauders is completely broken in regards to probing – if a Marauder (I am using a Golem in testing, which has the highest base signature radius) is in Bastion, with a single faction sensor booster loaded with ECCM scripts, it requires perfect scan skills, perfect spaceship command skills for covops/t3 subsystems, Mid-grade virtues, hardwirings, 2 Gravity capacitor rigs, and at least 1 rangefinding array in the mids.
So far, with testing if I attain just over 100 probe strength, I can barely scan a marauder fit as described above, using the most expensive implant set and hardwiring, and with perfect ship/scan skills.
Marauders are completely safe in deadspace to most of the game, coupled with the insane amount of damage they can put out now, there is very, very little risk to people flying marauders in DED deadspace.
EDIT: this is with Gravimetric Sensor Compensation level 0. So add 20% more Sensor Strength to the hull.
EDIT 2: As for a fix, if the Bastion module applies a “100% ECM resistance” bonus to the hull, why is the 1000% sensor strength bonus even there? Remove that, and it’d be balanced – it cant’ be jammed in bastion, and can be probed.
