legion = bad
loki = ok
proteus = awesome
proteus has a 100m3 drone bay and 25 bandwidth from an engineering subsys, whereas the loki has to fit specific offensive subsys to get drones.
proteus with covops cloak can still do huge dps.
i fly a cloaking unbubblable probing 90k shield buffer loki and its insane fun
and yess i got my loki hull for 260m and the subsystems were 50m each for 3 and 25m for the other 2 IIRC.
