I think you misunderstand what Lyraeus is saying; this is not unique to Armada, but is completely normal for this style of game
Is it though? 'Naval' wargames in my experience have no cards like this. Dystopian wars, BFG, Halo Fleet Battles, Man 'o War, etc have no card system like this.
And yes, I'm 100% aware that FFG would be doing themselves out of cash by not making the cards mandatory, but that's not a good enough reason for me to be happy with their decision. I don't like it.
