With respect Keyser, I think you're wrong. Both in your predicted snowball direction if you make these changes, and in yours and the balance team's assessment of how big a problem this is, how high priority it needs to be. We finally have the land game largely in a place where tech advancement happens nicely, nothing is overwhelming, and there's plenty of variety. Air and Navy are both still absolutely screwed up.
When I say "Dynamic", what I mean is "Not solved". On land, unpredictable things can happen and strategy is not set at the start of the game. There's no single path through the game on land without interruption. The same is untrue for both Air and Navy - They've been solved, and they've been solved because they have not fundamentally changed since the very... primitive balance given to us by GPG.
GPG's land balance was solved inside about 6 months of release: T1 spam won, UEF Percival won the lategame, and most units aren't worth building. We have now thoroughly changed this, and the game is now more dynamic.
In my opinion, both of them need completely tearing down and rebuilding from the ground up for greater dynamism. The brick wall of denial I encountered here in FAF is one reason I just gave up and decided if this is going to be solved, it will not be by FAF, it will be by a fan of the game making an entirely new game.
