So, I dunno if this is a universal experience or not, but I have found each successive wave has a longer "shelf life" for me. Armada has done such a fine job of keeping its whole pool of ships relevant and viable that it takes longer and longer for me to need new stuff as each new wave is released while I run through all the things I want to try. And this wave, which I shall dub the wave of a thousand squadrons, is taking me forever to even scratch the surface on.
So I guess I'm fine with a nice long FFG style wait until the next one.
And I'd love to see a new campaign again. Maybe with some new titles. Because that may have been the single most brilliant idea ever.
