Thanks for the answer-I figured that was the case but didn't know if I was missing something.
I was generally aware of the changes to weapons, but eliminating an entire line of defenses and sensors doesn't make a lot of sense to me regardless of those changes. In the first place it seems to me that point defense and ECM would be a thing with civilizations capable of interstellar travel in a universe that still uses guided missiles as a form of attack. Using armor and shields to absorb missile impacts instead of merely avoiding being hit in the first place seems pretty common sense. Obviously ECM wouldn't be effective against rail guns or beam weapons because there is not guidance system in either case, but it would come in handy to interrupt missile systems.
I realize it's early days and things can and likely will "evolve" with further iterations, but I don't like this change.
