Wait. You do realize that RBD is a defensive upgrade and an ISD doesn't have that. It would need Minister Tua and she is limited to one ship. So your fear of three ISD's having it is wrong.Armada seems to be vulnerable to huge swings in power-builds and combos. For a while it was Demolisher, an auto-include for any Imp fleet, later Ackbar had a period of apparent domination. NOW, it seems to me that Reinforced Blast Doors is going to bring back the triple ISD + motti build. Just to reiterate, an ISD II with Motti and blast doors has an effective 17 Hull points. This seems insane to me? 3 of those seems unbeatable.
Also as mentioned here in this thread and also by myself in the preview thread ECM's would be way better than RBD for a large ship like the ISD. So your fear are not justified.
ISD-IIs can take defensive upgrades natively.
